Collection Method: clinical testing

The c.49C>G (p.R17G) alteration is located in exon 3 (coding exon 1) of the ZDHHC16 gene. This alteration results from a C to G substitution at nucleotide position 49, causing the arginine (R) at amino acid position 17 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
