Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_001305581.2(LRMDA):​c.517-55537G>A variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.556 in 151,824 control chromosomes in the GnomAD database, including 24,780 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.56 (24780 hom., cov: 31)
• Consequence: LRMDA NM_001305581.2 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.0780

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.753 is higher than 0.05.
