Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001146684.3(RNF222):c.260C>T(p.Thr87Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000787 in 1,550,784 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 11/19 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. T87K) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.260C>T (p.T87M) alteration is located in exon 3 (coding exon 1) of the RNF222 gene. This alteration results from a C to T substitution at nucleotide position 260, causing the threonine (T) at amino acid position 87 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
