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 Benign. Variant got -7 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.34).
BP6
Variant 20-48988541-C-T is Benign according to our data. Variant chr20-48988541-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 434281.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
Synonymous conserved (PhyloP=2.25 with no splicing effect.
BS1
Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.000024 (35/1461374) while in subpopulation AMR AF= 0.0000895 (4/44712). AF 95% confidence interval is 0.0000298. There are 0 homozygotes in gnomad4_exome. There are 16 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
