CNOT3 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BS1: Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.000212 (41/193610) while in subpopulation SAS AF= 0.00109 (41/37480). AF 95% confidence interval is 0.000829. There are 1 homozygotes in gnomad4_exome. There are 33 alleles in male gnomad4_exome subpopulation. Median coverage is 0. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 5 AD gene.
