The c.34G>A (p.A12T) alteration is located in exon 2 (coding exon 1) of the GSDMA gene. This alteration results from a G to A substitution at nucleotide position 34, causing the alanine (A) at amino acid position 12 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
