Ambry Genetics

Apr 07, 2023

The c.850C>T (p.R284W) alteration is located in exon 4 (coding exon 4) of the CDYL2 gene. This alteration results from a C to T substitution at nucleotide position 850, causing the arginine (R) at amino acid position 284 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
