Genes affected

EFCAB8 (HGNC:34532): (EF-hand calcium binding domain 8) Predicted to enable calcium ion binding activity. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.015 (2283/152328) while in subpopulation SAS AF = 0.0437 (211/4824). AF 95% confidence interval is 0.0389. There are 26 homozygotes in GnomAd4. There are 1151 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 26 AR gene
