The c.694C>T (p.P232S) alteration is located in exon 6 (coding exon 5) of the RPUSD1 gene. This alteration results from a C to T substitution at nucleotide position 694, causing the proline (P) at amino acid position 232 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
