non-Syndromic Hearing Loss (NSHL) is a common defect in humans. Variants of MARVELD2 at the DFNB49 locus have been shown to cause bilateral, moderate to profound NSHL. However, the role of MARVELD2 in NSHL susceptibility in the chinese population has not been studied. Here we conducted a case-control study in an eastern chinese population to profile the spectrum and frequency of MARVELD2 variants, as well as the association of MARVELD2 gene variants with NSHL. Our results showed that variants identified in the chinese population are significantly different from those reported in Slovak, Hungarian, and Czech Roma, as well as Pakistani families. We identified 11 variants in a cohort of 283 NSHL cases. Through Sanger sequencing and bioinformatics analysis, we found that c.730G>A variant has detrimental effects in the eastern chinese population, and may have relatively high correlation with NSHL pathogenicity.

中国人群中非综合征耳聋相关MARVELD2 (DFNB49)基因新单核苷酸多态性位点分析

创新点:发现MARVELD2突变频谱具有明显种族特异性.中国NSHL人群中的突变位点及频率不同于已报道的其他人群,并首次筛选到新致聋候选突变MARVELD2 c.730G>A.本研究有助于进一步阐释MARVELD2在NSHL中的作用.
