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 creates a premature translational stop signal (p.Arg194*) in the C10orf11 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 5 amino acid(s) of the C10orf11 protein. This variant is present in population databases (rs587776952, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with albinism (PMID: 23395477). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 41916). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this premature translational stop signal affects C10orf11 function (PMID: 23395477). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
