The c.604C>T (p.P202S) alteration is located in exon 5 (coding exon 5) of the KHDRBS2 gene. This alteration results from a C to T substitution at nucleotide position 604, causing the proline (P) at amino acid position 202 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
