Genes affected

STX17 (HGNC:11432): (syntaxin 17) Enables SNAP receptor activity; SNARE binding activity; and protein phosphatase binding activity. Involved in several processes, including autophagosome membrane docking; endoplasmic reticulum to Golgi vesicle-mediated transport; and endoplasmic reticulum-Golgi intermediate compartment organization. Acts upstream of or within protein localization to phagophore assembly site. Located in several cellular components, including autophagosome membrane; endoplasmic reticulum-Golgi intermediate compartment; and mitochondria-associated endoplasmic reticulum membrane. Part of SNARE complex. Colocalizes with HOPS complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.71 is higher than 0.05.
