Ambry Genetics

Nov 10, 2023

The c.617C>T (p.A206V) alteration is located in exon 2 (coding exon 1) of the DNAJC22 gene. This alteration results from a C to T substitution at nucleotide position 617, causing the alanine (A) at amino acid position 206 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
