Genetic Variant ZNF250:p.Arg170His (chr8-144882674-C-T) – ACMG Classification: Likely_benign (-4 pts)

Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong

The NM_001109689.4(ZNF250):c.509G>A(p.Arg170His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000477 in 1,613,848 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 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. R170G) has been classified as Uncertain significance.

The c.524G>A (p.R175H) alteration is located in exon 6 (coding exon 5) of the ZNF250 gene. This alteration results from a G to A substitution at nucleotide position 524, causing the arginine (R) at amino acid position 175 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
