Genes affected
GAL (HGNC:4114): (galanin and GMAP prepropeptide) This gene encodes a neuroendocrine peptide that is widely expressed in the central and peripheral nervous systems and also the gastrointestinal tract, pancreas, adrenal gland and urogenital tract. The encoded protein is a precursor that is proteolytically processed to generate two mature peptides: galanin and galanin message-associated peptide (GMAP). Galanin has diverse physiological functions including nociception, feeding and energy homeostasis, osmotic regulation and water balance. GMAP has been demonstrated to possess antifungal activity and hypothesized to be part of the innate immune system. [provided by RefSeq, Jul 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.43G>A (p.A15T) alteration is located in exon 2 (coding exon 1) of the GAL gene. This alteration results from a G to A substitution at nucleotide position 43, causing the alanine (A) at amino acid position 15 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Familial temporal lobe epilepsy 8 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 31, 2022In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The threonine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 574523). This variant has not been reported in the literature in individuals affected with GAL-related conditions. This variant is present in population databases (rs753843211, gnomAD 0.03%). This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 15 of the GAL protein (p.Ala15Thr). -
