Genes affected

SNTG1 (HGNC:13740): (syntrophin gamma 1) The protein encoded by this gene is a member of the syntrophin family. Syntrophins are cytoplasmic peripheral membrane proteins that typically contain 2 pleckstrin homology (PH) domains, a PDZ domain that bisects the first PH domain, and a C-terminal domain that mediates dystrophin binding. This family member plays a role in mediating gamma-enolase trafficking to the plasma membrane and in enhancing its neurotrophic activity. Mutations in this gene are associated with idiopathic scoliosis. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Mar 2016]

The c.493A>G (p.T165A) alteration is located in exon 10 (coding exon 8) of the SNTG1 gene. This alteration results from a A to G substitution at nucleotide position 493, causing the threonine (T) at amino acid position 165 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
