Doyne honeycomb retinal dystrophy (DHRD), also termed malattia leventinese (MLVT), is a dominantly inherited ocular disease characterized by the progressive accumulation of macular and peripapillary drusenoid material beneath the retinal pigment epithelium in the Bruch membrane. In all affected individuals genetically characterized to date, DHRD/MLVT is caused by a single heterozygous p.Arg345Trp missense variant in the EGF‐containing fibulin‐like extracellular matrix protein 1, EFEMP1. Recently, pathogenic variants in the EFEMP1 gene have also been demonstrated in several families with juvenile or adult‐onset hereditary isolated glaucoma. Here, we describe a family featuring a unique phenotype of juvenile glaucoma and DHRD/MLVT caused by a novel EFEMP1 variant. Our results expand both the ocular phenotype associated with EFEMP1 variants and the molecular spectrum causing DHRD by describing the first non‐p.Arg345Trp EFEMP1 pathogenic allele.

Differences of sex development (DSDs) are a heterogeneous group of congenital conditions in which chromosomal, gonadal, or anatomical sex does not match. The broad spectrum of phenotypes associated with DSDs requires accurate diagnosis, which influences the care and quality of life of affected patients. The decreasing costs of next‐generation sequencing (NGS) and international research collaborations in rare diseases have allowed the identification of new genes associated with DSDs. Recently, Hughes et al. in 2020 reported the association of loss‐of‐function (LoF) variants in PPP1R12A with morphological anomalies of the midline, including holoprosencephaly and urogenital malformations, also known as genitourinary and/or brain malformation syndrome (OMIM #618820). In this report, we describe a Mexican individual with hypertelorism, multiple skin hemangiomas, testicular atrophy, and sex reversal, in whom a c.1880delC frameshift variant in PPP1R12A was detected by exome sequencing. Segregation analysis confirmed it as a de novo variant through Sanger sequencing. The main objective of this report is to expand PPP1R12A‐related urogenital and/or brain malformation syndrome.

Phelan-McDermid syndrome (PMS) is a rare genetic neurodevelopmental disorder that results from the loss of one functional copy of the SHANK3 gene. While many clinical features of PMS are well-understood, there is currently limited literature on cardiovascular abnormalities in PMS. This report aims to evaluate the prevalence of aortic root dilation (ARD) among individuals with PMS and to understand if underlying genetic variation relates to risk for ARD. We present findings from 59 participants collected from a multisite observational study evaluating the phenotype and natural history of PMS. Individual echocardiographic and genetic reports were analyzed for aortic root measurements and genetic variant data, respectively. Our a priori hypothesis was that participants with chromosome 22 deletions with hg19 start coordinates on or before 49,900,000 (larger deletions) would have more instances of ARD than participants with deletion start coordinates after 49,900,000 (smaller deletions). Eight participants (14%) had ARD, and its presence was statistically significantly associated with large deletions (p = 0.047). Relatedly, participants with ARD had significantly more genes deleted on chromosome 22 than participants without ARD (p = 0.013). These results could aid in the identification of individuals with PMS who are at higher risk for ARD.

The rapid development and clinical application of sequencing technologies enable the genetic diagnosis of inherited deafness. P2RX2, as the gene responsible for autosomal dominant non‐syndromic deafness‐41 (DFNA41), has been proven to be essential for life‐long normal hearing and for the protection of noise‐induced hearing loss (NIHL). Our present study reports a missense variant in the P2RX2 gene (c.178G > T (p.V60L)), for the second time worldwide, in a five‐generation kindred living in Henan, China. Despite carrying the same variant, the affected members in this family appear to present with earlier‐onset hearing loss and poorer hearing compared to the original DFNA41 families. In addition, this study supplements some content that was not covered in previous reports. We quantitatively evaluated the pain perception ability of some members using the Pain Vision PS‐2100 system, and further found an interesting clinical manifestation, that is, hyperalgesia, in heterozygotes for P2RX2 p.V60L. The cochlear implant (CI) was also provided for the proband of profound deafness, resulting in satisfactory clinical outcomes. Finally, we carried out a systematic review of recently published articles on the P2RX2 gene, which is beneficial for better understanding the role of the P2RX2 gene in the auditory system and the pathogenic mechanisms in sensorineural hearing loss (SNHL).

The recurrent chromosome 16p11.2 BP4‐BP5 microdeletion (MIM #611913) predisposes to a neurodevelopmental disorder with variable associated congenital anomalies and susceptibility to early‐onset obesity. We identified 22 new individuals with proximal 16p11.2 deletions through retrospective data analysis at our institution and performed phenotyping through in‐depth chart review. Our cohort exhibited a spectrum of neurodevelopmental abnormalities largely consistent with other publications, however they also were found to have a higher rate than expected of congenital anomalies, some of which have not yet been reported in association with 16p11.2 microdeletions to our knowledge. This series contributes to the body of data on this population, which we anticipate will continue to evolve along with increased uptake of genetic testing.
