Genes affected

ENSG00000268400 (HGNC:):

STXBP2 (HGNC:11445): (syntaxin binding protein 2) This gene encodes a member of the STXBP/unc-18/SEC1 family. The encoded protein is involved in intracellular trafficking, control of SNARE (soluble NSF attachment protein receptor) complex assembly, and the release of cytotoxic granules by natural killer cells. Mutations in this gene are associated with familial hemophagocytic lymphohistiocytosis. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Jan 2013]

PCP2 (HGNC:30209): (Purkinje cell protein 2) Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of catalytic activity. Predicted to act upstream of or within rhodopsin mediated signaling pathway. Predicted to be located in neuronal cell body. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
