Genes affected

LRMDA (HGNC:23405): (leucine rich melanocyte differentiation associated) This gene encodes a leucine-rich repeat protein. The encoded protein is thought to play a role in melanocyte differentiation. Mutations in this gene have been associated with autosomal recessive oculocutaneous albinism 7 (OCA7). Alternatively spliced transcript variants have been identified. [provided by RefSeq, Mar 2015]

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 9 of the C10orf11 protein (p.Gly9Ser). This variant is present in population databases (rs745930126, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with C10orf11-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
