Genes affected

GALP (HGNC:24840): (galanin like peptide) This gene encodes a member of the galanin family of neuropeptides. The encoded protein binds galanin receptors 1, 2 and 3 with the highest affinity for galanin receptor 3 and has been implicated in biological processes involving the central nervous system including hypothalamic regulation of metabolism and reproduction. A peptide encoded by a splice variant of this gene, termed alarin, has vasoactive properties, displays antimicrobial activity against E. coli, and may serve as a marker for neuroblastic tumors.[provided by RefSeq, Nov 2014]

Ambry Genetics

Feb 22, 2023

The c.290T>C (p.I97T) alteration is located in exon 5 (coding exon 4) of the GALP gene. This alteration results from a T to C substitution at nucleotide position 290, causing the isoleucine (I) at amino acid position 97 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
