The c.2872G>A (p.A958T) alteration is located in exon 8 (coding exon 6) of the ZNF445 gene. This alteration results from a G to A substitution at nucleotide position 2872, causing the alanine (A) at amino acid position 958 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
