The c.226A>G (p.T76A) alteration is located in exon 2 (coding exon 2) of the ZFP28 gene. This alteration results from a A to G substitution at nucleotide position 226, causing the threonine (T) at amino acid position 76 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
