The c.673A>G (p.I225V) alteration is located in exon 6 (coding exon 4) of the MTCL1 gene. This alteration results from a A to G substitution at nucleotide position 673, causing the isoleucine (I) at amino acid position 225 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
