ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV001000772 SCV001157825 uncertain significance Leber congenital amaurosis 12 2018-09-14 criteria provided, single submitter clinical testing The RD3 c.583G>T; p.Asp195Tyr variant (rs779496653), to our knowledge, is not reported in the medical literature or in gene-specific databases. The variant is found in the general population in 5 out of 262894 alleles in the Genome Aggregation Database. Another variant in the same codon, p.Asp195Val, is found in the general population with an allele frequency of 1% (2509/262664 allele, including 29 homozygotes) and is described as benign or likely benign in the ClinVar database (Variation ID: 445480). The aspartic acid at this position is highly conserved but computational analyses (SIFT: Damaging, PolyPhen-2:Benign) predict conflicting effects of this variant on protein structure/function. Although there are indications that this variant may not be pathogenic, the clinical significance of this variant is uncertain at this time. Pathogenic RD3 variants are causative for autosomal recessive Leber congenital amaurosis (MIM: 610612).
