The c.137T>A (p.L46Q) alteration is located in exon 2 (coding exon 2) of the MTG1 gene. This alteration results from a T to A substitution at nucleotide position 137, causing the leucine (L) at amino acid position 46 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
