Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_020828.2(ZFP28):c.68C>T(p.Thr23Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000404 in 1,535,456 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T23R) has been classified as Uncertain significance.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.68C>T (p.T23I) alteration is located in exon 1 (coding exon 1) of the ZFP28 gene. This alteration results from a C to T substitution at nucleotide position 68, causing the threonine (T) at amino acid position 23 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
