The c.468C>A (p.F156L) alteration is located in exon 3 (coding exon 2) of the ZDHHC23 gene. This alteration results from a C to A substitution at nucleotide position 468, causing the phenylalanine (F) at amino acid position 156 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
