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]

LRMDA Gene-Disease associations (from GenCC):

• oculocutaneous albinism type 7

  Inheritance: AR Classification: STRONG, SUPPORTIVE Submitted by: Labcorp Genetics (formerly Invitae), G2P, Orphanet

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.59).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.524 is higher than 0.05.
