The c.359A>G (p.Y120C) alteration is located in exon 4 (coding exon 3) of the DNAJC16 gene. This alteration results from a A to G substitution at nucleotide position 359, causing the tyrosine (Y) at amino acid position 120 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
