The c.550C>A (p.R184S) alteration is located in exon 4 (coding exon 4) of the CILP2 gene. This alteration results from a C to A substitution at nucleotide position 550, causing the arginine (R) at amino acid position 184 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
