Genes affected

TBC1D14 (HGNC:29246): (TBC1 domain family member 14) Enables protein kinase binding activity. Involved in negative regulation of autophagy; recycling endosome to Golgi transport; and regulation of autophagosome assembly. Located in several cellular components, including Golgi apparatus; autophagosome; and recycling endosome. [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=-0.99).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.137 is higher than 0.05.
