The c.775G>A (p.A259T) alteration is located in exon 7 (coding exon 5) of the ZNF385B gene. This alteration results from a G to A substitution at nucleotide position 775, causing the alanine (A) at amino acid position 259 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
