Background: Voltage-gated sodium channels are protein complexes composed of 2 subunits, namely, pore-forming α- and regulatory β-subunits. A β-subunit consists of 5 proteins encoded by 4 genes (i.e., SCN1B-SCN4B).

Summary: β1-Subunits regulate sodium ion channel functions, including gating properties, subcellular localization, and kinetics. Key Message: Sodium channel β1- and its variant β1B-subunits are encoded by SCN1B. These variants are associated with many human diseases, such as epilepsy, Brugada syndrome, Dravet syndrome, and cancers. On the basis of previous research, we aimed to provide an overview of the structure, expression, and involvement of SCN1B in physiological processes and focused on its role in diseases.

Objectives: Nonsyndromic hearing loss (NSHL) is the most frequent type of hereditary hearing impairment. Here, we explored the underlying genetic cause of NSHL in a three-generation family using whole-exome sequencing. The proband had concomitant NSHL and rare 48,XXYY Klinefelter syndrome.

Material and methods: Genomic DNA was extracted from the peripheral blood of the proband and their family members. Sanger sequencing and pedigree verification were performed on the pathogenic variants filtered by whole-exome sequencing. The function of the variants was analyzed using bioinformatics software.

Results: The proband was digenic heterozygous for p.V37I in the GJB2 gene and p.L347I in the MYO7A gene. The proband's mother had normal hearing and did not have any variant. The proband's father and uncle both had NSHL and were compound for the GJB2 p.V37I and MYO7A p.L347I variants, thus indicating a possible GJB2/MYO7A digenic inheritance of NSHL. 48,XXYY Klinefelter syndrome was discovered in the proband after the karyotype analysis, while his parents both had normal karyotypes.

Conclusions: Our findings reported a putative GJB2/MYO7A digenic inheritance form of hearing loss, expanding the genotype and phenotype spectrum of NSHL. In addition, this is the first report of concomitant NSHL and 48,XXYY syndrome.

目的:非综合征性听力损失(NSHL)是最常见的遗传性听力障碍类型。在这里,我们利用全外显子组测序技术探索了一个三代家族中NSHL的潜在遗传原因。先证者合并NSHL和罕见的48,xxyy Klinefelter综合征。材料和方法:先证者及其家族成员外周血中提取基因组DNA。对全外显子组测序筛选的致病变异进行Sanger测序和家系验证。利用生物信息学软件分析变异的功能。结果:先证者GJB2基因p.V37I和MYO7A基因p.L347I为基因杂合。先证者的母亲听力正常,没有任何变异。先证者的父亲和叔叔都患有NSHL,并且是GJB2 p.V37I和MYO7A p.L347I变体的复合,因此表明NSHL可能存在GJB2/MYO7A基因遗传。48、先证者经核型分析发现XXYY Klinefelter综合征,而其父母核型均正常。结论:我们的研究结果报道了一种推测的GJB2/MYO7A基因遗传形式的听力损失,扩大了NSHL的基因型和表型谱。此外,这是首次报道NSHL合并48,xxyy综合征。

Introduction: Auditory neuropathy is a hearing disorder where outer hair cell function within the cochlea is normal, but inner hair cell and/or the auditory nerve function is disrupted. It is a heterogeneous disorder, which can have either congenital or acquired causes.

Methods: We found a disease-segregating mutation in the X-linked AIFM1 gene through whole-exome sequencing, encoding the apoptosis-inducing factor mitochondrion-associated 1.

Results: The impact of the c.1045A>G; p.(Ser349Gly) mutation on the AIFM1 protein was predicted using different bioinformatics tools. The pedigree analysis in the examined family was consistent with X-linked dominant inheritance.

Discussion/conclusion: To our knowledge, this is the first study that identifies a mutation in the AIFM1 gene in Moroccan patients suffering from X-linked auditory neuropathy.

Multiple Linear Regression Allows Weighted Burden Analysis of Rare Coding Variants in an Ethnically Heterogeneous Population. 多元线性回归允许加权负担分析罕见的编码变异在种族异质人群。
IF 1.8 4区 生物学 Q3 Biochemistry, Genetics and Molecular Biology Pub Date : 2020-01-01 Epub Date: 2021-01-07 DOI: 10.1159/000512576

Weighted burden analysis has been used in exome-sequenced case-control studies to identify genes in which there is an excess of rare and/or functional variants associated with phenotype. Implementation in a ridge regression framework allows simultaneous analysis of all variants along with relevant covariates, such as population principal components. In order to apply the approach to a quantitative phenotype, a weighted burden score is derived for each subject and included in a linear regression analysis. The weighting scheme is adjusted in order to apply differential weights to rare and very rare variants and a score is derived based on both the frequency and predicted effect of each variant. When applied to an ethnically heterogeneous dataset consisting of 49,790 exome-sequenced UK Biobank subjects and using body mass index as the phenotype, the method produces a very inflated test statistic. However, this is almost completely corrected by including 20 population principal components as covariates. When this is done, the top 30 genes include a few which are quite plausibly associated with the phenotype, including LYPLAL1 and NSDHL. This approach offers a way to carry out gene-based analyses of rare variants identified by exome sequencing in heterogeneous datasets without requiring that data from ethnic minority subjects be discarded. This research has been conducted using the UK Biobank Resource.

加权负担分析已被用于外显子组测序的病例对照研究,以确定存在与表型相关的过量罕见和/或功能变异的基因。在岭回归框架中实现允许同时分析所有变量以及相关协变量,例如人口主成分。为了将该方法应用于定量表型,为每个受试者导出加权负担评分,并将其纳入线性回归分析。对权重方案进行调整,以便对罕见和非常罕见的变量应用不同的权重,并根据每种变量的频率和预测效果得出一个分数。当应用于由49,790名英国生物银行外显子组测序受试者组成的种族异质性数据集并使用体重指数作为表型时,该方法产生了非常膨胀的测试统计量。然而,通过将20个总体主成分作为协变量,这几乎可以完全纠正。当这样做时,前30个基因包括一些很可能与表型相关的基因,包括LYPLAL1和NSDHL。该方法提供了一种对异质数据集中通过外显子组测序鉴定的罕见变异进行基于基因的分析的方法,而不需要丢弃来自少数民族受试者的数据。这项研究是利用英国生物银行资源进行的。

Introduction: Breast cancer is a heterogeneous and multifactorial disease. TP53 and PAI-1 as important tumor suppressor genes are involved in the development, invasion, and metastasis of many cancers. This study's objective was to demonstrate the combined genotype effects of these 2 genes by investigating their single nucleotide polymorphisms.

Methods: In this case-control study, 200 individuals with breast cancer and 179 healthy individuals were studied. The genotypes were determined using the tetra-ARMS method. For data analysis, MDR, online javstat statistics package, and SPSS v.24 software were used. Also, in silico studies on the estimated effects of each of these polymorphisms were performed.

Results: We showed a novel gene-gene interaction of these 2 genes and demonstrated a strong synergistic interaction for TP53/PAI-1, moderate synergistic interaction for PAI-1/age, and correlation for TP53/age. On the other hand, there was no association between the allelic and genotype frequency alone and in combination, with case-control status, using the parametric method, between TP53 and PAI-1.

Discussion/conclusion: Our findings suggest that the polymorphism of codon 72 of the TP53 gene was significantly associated with tumor stage (p < 0.023). In conclusion, we showed a gene-gene interaction between TP53 and PAI-1, in combination, using the MDR method.

乳腺癌是一种异质性和多因素的疾病。TP53和PAI-1作为重要的抑癌基因,参与了多种肿瘤的发生、侵袭和转移。本研究的目的是通过研究这两个基因的单核苷酸多态性来证明它们的联合基因型效应。方法:在本病例对照研究中,对200例乳腺癌患者和179例健康人进行了研究。采用4 - arms法测定基因型。数据分析采用MDR、在线javstat统计软件包和SPSS v.24软件。此外,对每种多态性的估计影响进行了计算机研究。结果:我们发现了这两个基因的一种新的基因-基因相互作用,并证明了TP53/PAI-1的强协同相互作用,PAI-1/age的中等协同相互作用,以及TP53/age的相关性。另一方面,TP53和PAI-1之间的等位基因和基因型频率单独或联合存在无相关性,使用参数法,在病例对照状态下。讨论/结论:TP53基因密码子72多态性与肿瘤分期有显著相关性(p < 0.023)。总之,我们使用MDR方法发现TP53和PAI-1之间存在基因-基因相互作用。

Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is caused by one or more mutations in the G6PD gene on chromosome X. This study aimed to characterize the G6PD gene variant distribution in Shenzhen of Guangdong province.

Methods: A total of 33,562 individuals were selected at the hospital for retrospective analysis, of which 1,213 cases with enzymatic activity-confirmed G6PD deficiency were screened for G6PD gene variants. Amplification refractory mutation system PCR was first used to screen the 6 dominant mutants in the Chinese population (c.1376G>T, c.1388G>A, c.95A>G, c.1024C>T, c.392G>T, and c.871G>A). If the 6 hotspot variants were not found, next-generation sequencing was then performed. Finally, Sanger sequencing was used to verify all the mutations.

Results: The incidence of G6PD deficiency in this study was 3.54%. A total of 26 kinds of mutants were found in the coding region, except for c.-8-624T>C, which was in the noncoding region. c.1376G>T and c.1388G>A, both located in exon 12, were the top 2 mutants, accounting for 68.43% of all individuals. The 6 hotspot mutations had a cumulative proportion of 94.02%.

Conclusions: This study provided detailed characteristics of G6PD gene variants in Shenzhen, and the results would be valuable to enrich the knowledge of G6PD deficiency.

背景:葡萄糖-6-磷酸脱氢酶(G6PD)缺乏症是由x染色体上G6PD基因的一个或多个突变引起的。本研究旨在研究G6PD基因在广东深圳地区的变异分布特征。方法:选取该院33562例患者进行回顾性分析,其中1213例酶活性证实的G6PD缺乏症患者进行G6PD基因变异筛查。首次采用扩增难解突变系统PCR筛选中国人群中6个显性突变体(c.1376G>T、c.1388G>A、c.95A>G、c.1024C>T、c.392G>T和c.871G>A)。如果未发现6个热点变异,则进行下一代测序。最后,使用Sanger测序对所有突变进行验证。结果:本研究G6PD缺乏症发生率为3.54%。除C -8- 624t >C位于非编码区外,编码区共发现26种突变体。位于第12外显子的c.1376G>T和c.1388G>A是前2位突变体,占总个体的68.43%。6个热点突变的累积比例为94.02%。结论:本研究提供了深圳地区G6PD基因变异的详细特征,对丰富G6PD缺乏症的认识具有重要价值。

Background: Male infertility is a major health issue worldwide. Y chromosome microdeletions are well-characterized genetic causes of male infertility. The association of partial AZFc deletions (gr/gr, b2/b3, and b1/b3) with male infertility is not well confirmed in diverse populations. The purpose of the present study was to investigate the frequency of partial AZFc deletions and their association with male infertility in a population from Northwestern China. Methods: Multiplex polymerase chain reaction was used to detect partial AZFc deletions in 228 infertile patients. We analyzed 141 cases of azoospermia (AS), 87 cases of oligozoospermia (OS), and 200 fertile controls. Results: Our data showed that the frequency of a b2/b3 deletion in infertile men, men with AS, men with OS, and controls was 3.51, 2.13, 5.75, and 0.00%, respectively. The frequency of this deletion was significantly different between the infertile group and the control group (3.51 vs. 0.00%, respectively, p = 0.021) and between the OS group and the control group (5.75 vs. 0.00%, respectively, p = 0.003). The frequency of a gr/gr deletion in each group was 11.84, 9.22, 16.09, and 7.50%, respectively. The frequency of a gr/gr deletion was significantly different between the OS group and the control group (16.09 vs. 7.50%, respectively, p = 0.026) but not between the infertile group and the control group (11.84 vs. 7.50%, p = 0.132) or the AS group and the control group (9.22 vs. 7.50%, p = 0.569). The frequency of a b1/b3 deletion was 0.44, 0.71, 0.00, and 3.00%, respectively. For this deletion, there was no significant difference between the infertile (0.44 vs. 3.00%, p = 0.089), AS (0.71 vs. 3.00%, p = 0.276), and OS groups (0.00 vs. 3.00%, p = 0.236) and the control group. Conclusions: Our results suggest that the b2/b3 deletion might be associated with male infertility and that the gr/gr deletion might be associated with spermatogenic failure in men with OS in Northwestern China (Ningxia).
背景:男性不育是世界范围内的一个主要健康问题。Y染色体微缺失是男性不育的典型遗传原因。AZFc部分缺失(gr/gr、b2/b3和b1/b3)与男性不育的相关性在不同人群中尚未得到很好的证实。本研究的目的是调查中国西北地区人群中AZFc部分缺失的频率及其与男性不育的关系。方法:应用多重聚合酶链反应检测228例不孕患者的AZFc部分缺失。我们分析了141例无精子症(AS)、87例少精症(OS)和200例可育对照。结果:我们的数据显示,不育男性、AS男性、OS男性和对照组的b2/b3缺失频率分别为3.51、2.13、5.75和0.00%。不孕组和对照组之间这种缺失的频率有显著差异(分别为3.51和0.00%,p=0.021),OS组和对照对照组之间(分别为5.75和0.00%)。各组的gr/gr缺失频率分别为11.84、9.22、16.09和7.50%。OS组和对照组之间的gr/gr缺失频率显著不同(分别为16.09%和7.50%,p=0.026),但不孕组和对照对照组之间(11.84和7.50%)或AS组和对照小组之间(9.22对7.50%,p=0.569)没有差异。b1/b3缺失频率分别为0.44%、0.71、0.00和3.00%。对于这种缺失,不孕组(0.44 vs.3.00%,p=0.089)、AS组(0.71 vs.3.00%,p=0.276)、OS组(0.00 vs.3.000%,p=0.236)与对照组之间没有显著差异。结论:我们的研究结果表明,b2/b3缺失可能与中国西北(宁夏)OS男性不育有关,gr/gr缺失可能与生精失败有关。

Mutations in the mesenchymal epithelial transition factor (MET) gene are frequently associated with multiple human cancers but can also lead to human non-syndromic autosomal recessive deafness (DFNB97). In the present study, we identified a novel homozygous missense mutation in the METgene causing a non-syndromic hearing impairment DFNB97 form. Whole-exome sequencing was performed to determine the genetic causes of hearing loss in a Moroccan consanguineous family with an affected daughter. The structural analysis of native and mutant in the SEMA domain of the MET receptor was investigated using a molecular dynamics simulation (MDS) approach. We identified a novel pathogenic homozygous c.948A>G (p.Ile316Met) mutation in the MET gene in one deaf Moroccan young girl carrying a total bilateral non-syndromic hearing impairment. The results of the MDS approach show that an Ile316Met mutation in the SEMA domain leads to protein flexibility loss. This may produce a major impact on the structural conformation of the MET receptor, which also affects the function and binding site of the receptor. This is the first time that a mutation in the MET gene is described in a Moroccan family. Moreover, this study reports the second family in the world associating deafness and mutation in the MET gene.
间充质-上皮转化因子(MET)基因的突变通常与多种人类癌症有关,但也可能导致人类非综合征常染色体隐性耳聋(DFNB97)。在本研究中,我们在MET基因中发现了一个新的纯合错义突变,导致非综合征性听力损伤DFNB97形式。在一个有患病女儿的摩洛哥近亲家庭中,进行了全外显子组测序,以确定听力损失的遗传原因。使用分子动力学模拟(MDS)方法研究MET受体SEMA结构域中天然和突变体的结构分析。我们在一名患有双侧非综合征性听力损伤的失聪摩洛哥年轻女孩的MET基因中发现了一个新的致病性纯合c.948A>G(p.Ile316Met)突变。MDS方法的结果表明,SEMA结构域中的Ile316Met突变导致蛋白质灵活性丧失。这可能对MET受体的结构构象产生重大影响,也影响受体的功能和结合位点。这是第一次在摩洛哥家族中描述MET基因的突变。此外,这项研究报告了世界上第二个将耳聋与MET基因突变联系起来的家族。
