Genes affected

ELOVL4 (HGNC:14415): (ELOVL fatty acid elongase 4) This gene encodes a membrane-bound protein which is a member of the ELO family, proteins which participate in the biosynthesis of fatty acids. Consistent with the expression of the encoded protein in photoreceptor cells of the retina, mutations and small deletions in this gene are associated with Stargardt-like macular dystrophy (STGD3) and autosomal dominant Stargardt-like macular dystrophy (ADMD), also referred to as autosomal dominant atrophic macular degeneration.

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.96).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000118 (18/151972) while in subpopulation AFR AF = 0.00041 (17/41434). AF 95% confidence interval is 0.000261. There are 0 homozygotes in GnomAd4. There are 8 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
