Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.718C>T (p.R240W) alteration is located in exon 9 (coding exon 8) of the PRR5L gene. This alteration results from a C to T substitution at nucleotide position 718, causing the arginine (R) at amino acid position 240 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
