The c.224G>A (p.R75H) alteration is located in exon 7 (coding exon 3) of the GPSM3 gene. This alteration results from a G to A substitution at nucleotide position 224, causing the arginine (R) at amino acid position 75 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
