Ambry Genetics

Dec 03, 2021

The c.781C>T (p.R261W) alteration is located in exon 4 (coding exon 4) of the ANKRD53 gene. This alteration results from a C to T substitution at nucleotide position 781, causing the arginine (R) at amino acid position 261 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
