The c.219G>C (p.Q73H) alteration is located in exon 7 (coding exon 3) of the GPSM3 gene. This alteration results from a G to C substitution at nucleotide position 219, causing the glutamine (Q) at amino acid position 73 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
