Collection Method: clinical testing

The c.1025C>T (p.P342L) alteration is located in exon 8 (coding exon 7) of the SLX4IP gene. This alteration results from a C to T substitution at nucleotide position 1025, causing the proline (P) at amino acid position 342 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
