Genes affected

ARFGEF2 (HGNC:15853): (ADP ribosylation factor guanine nucleotide exchange factor 2) ADP-ribosylation factors (ARFs) play an important role in intracellular vesicular trafficking. The protein encoded by this gene is involved in the activation of ARFs by accelerating replacement of bound GDP with GTP and is involved in Golgi transport. It contains a Sec7 domain, which may be responsible for its guanine-nucleotide exchange activity and also brefeldin A inhibition. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0000395 (6/151998) while in subpopulation NFE AF= 0.0000882 (6/68008). AF 95% confidence interval is 0.0000376. There are 0 homozygotes in gnomad4. There are 3 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
