ISY1-RAB43 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00714 (1085/152004) while in subpopulation AFR AF= 0.0197 (818/41446). AF 95% confidence interval is 0.0186. There are 8 homozygotes in gnomad4. There are 508 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 8 gene
