The c.652A>T (p.S218C) alteration is located in exon 3 (coding exon 2) of the RSRP1 gene. This alteration results from a A to T substitution at nucleotide position 652, causing the serine (S) at amino acid position 218 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
