Genes affected

TSPAN13 (HGNC:21643): (tetraspanin 13) The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0147 (2233/152328) while in subpopulation AFR AF= 0.0514 (2138/41564). AF 95% confidence interval is 0.0496. There are 62 homozygotes in gnomad4. There are 1052 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 62 AR gene
