Genes affected

EFCC1 (HGNC:25692): (EF-hand and coiled-coil domain containing 1) Predicted to enable calcium ion binding activity. Predicted to be active in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.01).
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.00103 (157/152302) while in subpopulation SAS AF= 0.0232 (112/4832). AF 95% confidence interval is 0.0197. There are 1 homozygotes in gnomad4. There are 105 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
