Ambry Genetics

Oct 02, 2023

The c.670C>T (p.R224W) alteration is located in exon 7 (coding exon 6) of the KRBA1 gene. This alteration results from a C to T substitution at nucleotide position 670, causing the arginine (R) at amino acid position 224 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
