Ambry Genetics

Dec 03, 2021

The c.181A>C (p.K61Q) alteration is located in exon 2 (coding exon 2) of the DNAJA4 gene. This alteration results from a A to C substitution at nucleotide position 181, causing the lysine (K) at amino acid position 61 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
