Collection Method:clinical testing

The c.203C>T (p.S68L) alteration is located in exon 2 (coding exon 1) of the CUL9 gene. This alteration results from a C to T substitution at nucleotide position 203, causing the serine (S) at amino acid position 68 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
