Genes affected

ECT2L (HGNC:21118): (epithelial cell transforming 2 like) Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of catalytic activity. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -9 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.003909439).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00696 (1059/152250) while in subpopulation AFR AF = 0.0234 (973/41540). AF 95% confidence interval is 0.0222. There are 8 homozygotes in GnomAd4. There are 506 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
• BS2: High Homozygotes in GnomAd4 at 8 AR gene
