Collection Method: clinical testing

The c.409C>T (p.P137S) alteration is located in exon 6 (coding exon 6) of the U2AF1L4 gene. This alteration results from a C to T substitution at nucleotide position 409, causing the proline (P) at amino acid position 137 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
