The c.550C>T (p.R184C) alteration is located in exon 3 (coding exon 2) of the XIRP2 gene. This alteration results from a C to T substitution at nucleotide position 550, causing the arginine (R) at amino acid position 184 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
