The c.412T>G (p.L138V) alteration is located in exon 8 (coding exon 4) of the GPSM3 gene. This alteration results from a T to G substitution at nucleotide position 412, causing the leucine (L) at amino acid position 138 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
