Collection Method:clinical testing

The c.548C>T (p.S183F) 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 548, causing the serine (S) at amino acid position 183 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
