Collection Method: clinical testing

The c.365G>A (p.R122H) alteration is located in exon 4 (coding exon 4) of the ZDHHC12 gene. This alteration results from a G to A substitution at nucleotide position 365, causing the arginine (R) at amino acid position 122 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
