The c.332C>G (p.A111G) alteration is located in exon 4 (coding exon 4) of the ZDHHC20 gene. This alteration results from a C to G substitution at nucleotide position 332, causing the alanine (A) at amino acid position 111 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
