The c.224C>A (p.S75Y) alteration is located in exon 2 (coding exon 2) of the PARM1 gene. This alteration results from a C to A substitution at nucleotide position 224, causing the serine (S) at amino acid position 75 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
