Ambry Genetics

Dec 09, 2023

The c.265C>T (p.R89W) alteration is located in exon 3 (coding exon 3) of the GRPEL1 gene. This alteration results from a C to T substitution at nucleotide position 265, causing the arginine (R) at amino acid position 89 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
