Genes affected

SLC24A4 (HGNC:10978): (solute carrier family 24 member 4) This gene encodes a sodium/potassium/calcium exchange protein. The encoded antiporter transports one calcium and one potassium ion in exchange for four sodium ions and has been implicated in amelogenesis and enamel maturation. Certain variants in this gene have been associated with skin, hair, and eye pigmentation, while other variants have been identified in people with hypomaturation-type amelogenesis imperfecta.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.857 is higher than 0.05.
