Collection Method: clinical testing

The c.660T>G (p.D220E) alteration is located in exon 5 (coding exon 5) of the ZFP28 gene. This alteration results from a T to G substitution at nucleotide position 660, causing the aspartic acid (D) at amino acid position 220 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
