Genes affected

MS4A4A (HGNC:13371): (membrane spanning 4-domains A4A) This gene encodes a member of the membrane-spanning 4A gene family. Members of this nascent protein family are characterized by common structural features, similar intron/exon splice boundaries, and display unique expression patterns in hematopoietic cells and nonlymphoid tissues. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.62).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.704 is higher than 0.05.
