The c.145G>T (p.D49Y) alteration is located in exon 2 (coding exon 1) of the ZDHHC23 gene. This alteration results from a G to T substitution at nucleotide position 145, causing the aspartic acid (D) at amino acid position 49 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
