Genes affected

STXBP5L (HGNC:30757): (syntaxin binding protein 5L) The protein encoded by this gene is similar to syntaxin-binding protein 5 and contains ten N-terminal WD40 repeats, four variable region WD40 repeats, and a C-terminal R-SNARE domain. Studies of the orthologous proteins in mouse and rat have shown that the encoded protein may inhibit exocytosis in neurosecretory cells, and may negatively regulate the secretion of insulin. A missense variant in this gene is likely the cause of an infantile-onset neurodegenerative disorder diagnosed in two siblings of consanguineous parents. [provided by RefSeq, Jan 2017]

Ambry Genetics

Mar 17, 2023

The c.155A>C (p.E52A) alteration is located in exon 2 (coding exon 1) of the STXBP5L gene. This alteration results from a A to C substitution at nucleotide position 155, causing the glutamic acid (E) at amino acid position 52 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
