Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_015042.2(ZNF609):c.809A>T(p.Asn270Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000219 in 1,461,840 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. N270K) has been classified as Uncertain significance.

The c.809A>T (p.N270I) alteration is located in exon 2 (coding exon 2) of the ZNF609 gene. This alteration results from a A to T substitution at nucleotide position 809, causing the asparagine (N) at amino acid position 270 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
