RCV001000880 | SCV001157962 | uncertain significance | Retinitis pigmentosa 38 | 2019-01-03 | criteria provided, single submitter | clinical testing | The MERTK c.520A>T; p.Ile174Phe variant (rs775179251), to our knowledge, is not reported in the medical literature or gene-specific databases. The variant is described in the general population with an allele frequency of 0.002% (4/251256 alleles) in the Genome Aggregation Database. The isoleucine at this position is conserved, but at least two mammals have a phenylalanine at this position, and computational algorithms (PolyPhen-2, SIFT) predict this variant is deleterious. Additionally, this variant occurs in the extracellular Ig domain and few missense variants verified to be pathogenic occur in this region (Audo 2018). However, due to limited information, the clinical significance of this variant cannot be determined with certainty. References: Audo I et al. MERTK mutation update in inherited retinal diseases.
