Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2 BP4

The NM_138300.4(PYGO2):​c.1168T>A​(p.Ser390Thr) variant causes a missense change. The variant allele was found at a frequency of 0.00000205 in 1,461,672 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S390P) has been classified as Uncertain significance.

Genes affected

PYGO2 (HGNC:30257): (pygopus family PHD finger 2) Predicted to enable several functions, including chromatin binding activity; histone acetyltransferase regulator activity; and histone binding activity. Predicted to be involved in kidney development and spermatid nucleus differentiation. Predicted to act upstream of or within several processes, including animal organ development; positive regulation of chromatin binding activity; and regulation of histone H3-K4 methylation. Part of beta-catenin-TCF complex. [provided by Alliance of Genome Resources, Apr 2022]
