The c.76G>A (p.A26T) alteration is located in exon 3 (coding exon 1) of the MTCL1 gene. This alteration results from a G to A substitution at nucleotide position 76, causing the alanine (A) at amino acid position 26 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
