Ambry Genetics

Jun 17, 2022

The c.640C>T (p.R214C) alteration is located in exon 4 (coding exon 4) of the METRN gene. This alteration results from a C to T substitution at nucleotide position 640, causing the arginine (R) at amino acid position 214 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
