The c.445G>A (p.A149T) alteration is located in exon 7 (coding exon 4) of the ZDHHC21 gene. This alteration results from a G to A substitution at nucleotide position 445, causing the alanine (A) at amino acid position 149 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
