Mutational screening of SLC39A5, LEPREL1 and LRPAP1 in a cohort of 187 high myopia patients
Abstract High myopia (HM) is a leading cause of mid-way blindness with a high heritability in East Asia. Although only a few disease genes have been reported, a small proportion of patients could be identified with genetic predispositions. In order to expand the mutation spectrum of the causative ge...

| Sumario: | Abstract High myopia (HM) is a leading cause of mid-way blindness with a high heritability in East Asia. Although only a few disease genes have been reported, a small proportion of patients could be identified with genetic predispositions. In order to expand the mutation spectrum of the causative genes in Chinese adult population, we investigated three genes, SLC39A5, LEPREL1 and LRPAP1, in a cohort of 187 independent Chinese patients with high myopia. Sanger sequencing was used to find possible pathogenic mutations, which were further screened in normal controls. After a pipeline of database and predictive assessments filtering, we, thereby, identified totally seven heterozygous mutations in the three genes. Among them, three novel missense mutations, c.860C > T, p.Pro287Leu and c.956G > C, p.Arg319Thr in SLC39A5, c.1982A > G, p.Lys661Arg in LEPREL1, were identified as potentially causative mutations. Additionally, the two heterozygous mutations (c.1582G > A, p.Ala528Thr; c.1982A > G, p.Lys661Arg) in one patient in LEPREL1 gene were reported in this study. Our findings will not only augment the mutation spectrum of these three genes, but also provide insights of the contribution of these genes to adult high myopia in Chinese. However, further studies are still needed to address the pathogenicity of each of the mutations reported in this study. |
