Genes affected

FAM13A (HGNC:19367): (family with sequence similarity 13 member A) Predicted to enable GTPase activator activity. Predicted to be involved in regulation of small GTPase mediated signal transduction. Predicted to be located in cytosol. Implicated in chronic obstructive pulmonary disease. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0147 (2236/152238) while in subpopulation AFR AF= 0.0508 (2111/41524). AF 95% confidence interval is 0.049. There are 58 homozygotes in gnomad4. There are 1006 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 58 AR gene
