Collection Method: clinical testing

The c.448G>A (p.D150N) alteration is located in exon 4 (coding exon 4) of the ZFP28 gene. This alteration results from a G to A substitution at nucleotide position 448, causing the aspartic acid (D) at amino acid position 150 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
