Collection Method: clinical testing

The c.1979A>G (p.N660S) alteration is located in exon 7 (coding exon 6) of the DNAJC14 gene. This alteration results from a A to G substitution at nucleotide position 1979, causing the asparagine (N) at amino acid position 660 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
