The c.506C>T (p.T169I) alteration is located in exon 4 (coding exon 4) of the ZFP28 gene. This alteration results from a C to T substitution at nucleotide position 506, causing the threonine (T) at amino acid position 169 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
