Ambry Genetics

May 25, 2022

The c.721C>T (p.R241W) alteration is located in exon 6 (coding exon 6) of the OLFM2 gene. This alteration results from a C to T substitution at nucleotide position 721, causing the arginine (R) at amino acid position 241 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
