Genes affected

STXBP4 (HGNC:19694): (syntaxin binding protein 4) Enables syntaxin binding activity. Involved in several processes, including positive regulation of cell cycle G1/S phase transition; positive regulation of keratinocyte proliferation; and protein stabilization. Located in extracellular exosome. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_addAF=-0.868523).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.886 is higher than 0.05.
