Genes affected

AP2B1 (HGNC:563): (adaptor related protein complex 2 subunit beta 1) The protein encoded by this gene is one of two large chain components of the assembly protein complex 2, which serves to link clathrin to receptors in coated vesicles. The encoded protein is found on the cytoplasmic face of coated vesicles in the plasma membrane. Two transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant 17-35578961-A-G is Benign according to our data. Variant chr17-35578961-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 1186416.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0105 (1607/152334) while in subpopulation AFR AF= 0.029 (1204/41582). AF 95% confidence interval is 0.0276. There are 23 homozygotes in gnomad4. There are 753 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1607 AD gene.
