Abstract
Neuromuscular scoliosis can be caused by muscular or nervous system dysfunction resulting from genetic variants. Variation in MYH7 may cause hypertrophic or dilated cardiomyopathy, skeletal myopathies, or a combination of both; however, scoliosis has rarely been reported. We analyzed a Chinese pedigree with two members suffering from scoliosis. Whole-exome sequencing identified a variant (NM_000257.4:c.2011C > T) of MYH7 that cosegregated with the scoliosis phenotype. The variant resulted in a change in the evolutionarily conserved amino acid residue 671 from arginine to cystine (p.R671C), which was predicted to disrupt the structure and function of the motor domain of the slow/β-cardiac myosin heavy chain encoded by MYH7. To date, 913 MYH7 variants were associated with cardiomyopathy and/or skeletal myopathies according to the Human Gene Mutation Database. However, only 15 cases of scoliosis have been reported. In our case, the c.2011C > T variant caused scoliosis with 100 % penetrance and hypertrophic cardiomyopathy with partial penetrance.
期刊介绍:
Open access, online only, peer-reviewed international journal in the Life Sciences, established in 2014 Biochemistry and Biophysics Reports (BB Reports) publishes original research in all aspects of Biochemistry, Biophysics and related areas like Molecular and Cell Biology. BB Reports welcomes solid though more preliminary, descriptive and small scale results if they have the potential to stimulate and/or contribute to future research, leading to new insights or hypothesis. Primary criteria for acceptance is that the work is original, scientifically and technically sound and provides valuable knowledge to life sciences research. We strongly believe all results deserve to be published and documented for the advancement of science. BB Reports specifically appreciates receiving reports on: Negative results, Replication studies, Reanalysis of previous datasets.
