The c.467C>T (p.A156V) alteration is located in exon 6 (coding exon 4) of the MTCL1 gene. This alteration results from a C to T substitution at nucleotide position 467, causing the alanine (A) at amino acid position 156 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
