Genes affected

ARL2BP (HGNC:17146): (ADP ribosylation factor like GTPase 2 binding protein) ADP-ribosylation factor (ARF)-like proteins (ARLs) comprise a functionally distinct group of the ARF family of RAS-related GTPases. The protein encoded by this gene binds to ARL2.GTP with high affinity but does not interact with ARL2.GDP, activated ARF, or RHO proteins. The lack of detectable membrane association of this protein or ARL2 upon activation of ARL2 is suggestive of actions distinct from those of the ARFs. This protein is considered to be the first ARL2-specific effector identified, due to its interaction with ARL2.GTP but lack of ARL2 GTPase-activating protein activity. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0035790205).

BP6

Variant 16-57249818-G-A is Benign according to our data. Variant chr16-57249818-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 402395.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.02 (3039/152328) while in subpopulation NFE AF = 0.0311 (2114/68028). AF 95% confidence interval is 0.03. There are 46 homozygotes in GnomAd4. There are 1342 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 46 AR,AD gene
