Ambry Genetics

May 31, 2023

The c.65T>C (p.M22T) alteration is located in exon 1 (coding exon 1) of the DNAJC27 gene. This alteration results from a T to C substitution at nucleotide position 65, causing the methionine (M) at amino acid position 22 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
