Genes affected

SEC16A (HGNC:29006): (SEC16 homolog A, endoplasmic reticulum export factor) This gene encodes a protein that forms part of the Sec16 complex. This protein has a role in protein transport from the endoplasmic reticulum (ER) to the Golgi and mediates COPII vesicle formation at the transitional ER. Alternative splicing results in multiple transcript variants that encode different protein isoforms. [provided by RefSeq, Feb 2013]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.73).
• BP6: Variant 9-136440101-G-C is Benign according to our data. Variant chr9-136440101-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 1212476.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High Homozygotes in GnomAd4 at 2 AR gene
