The c.39G>C (p.Q13H) alteration is located in exon 1 (coding exon 1) of the MTG1 gene. This alteration results from a G to C substitution at nucleotide position 39, causing the glutamine (Q) at amino acid position 13 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
