Genes affected

STIM2 (HGNC:19205): (stromal interaction molecule 2) This gene is a member of the stromal interaction molecule (STIM) family and likely arose, along with related family member STIM1, from a common ancestral gene. The encoded protein functions to regulate calcium concentrations in the cytosol and endoplasmic reticulum, and is involved in the activation of plasma membrane Orai Ca(2+) entry channels. This gene initiates translation from a non-AUG (UUG) start site. A signal peptide is cleaved from the resulting protein. Multiple transcript variants result from alternative splicing.

The c.115G>A (p.A39T) alteration is located in exon 1 (coding exon 1) of the STIM2 gene. This alteration results from a G to A substitution at nucleotide position 115, causing the alanine (A) at amino acid position 39 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
