Genes affected

INTS8 (HGNC:26048): (integrator complex subunit 8) This gene encodes a subunit of the Integrator complex which is involved in the cleavage of small nuclear RNAs U1 and U2 within the nucleus. The encoded protein associates with RNA polymerase II and is recruited to the U1 and U2 small nuclear RNA genes. Alternative splicing results in multiple transcript variants.

Variant summary: INTS8 c.736G>A (p.Glu246Lys) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0001 in 248394 control chromosomes. To our knowledge, no occurrence of c.736G>A in individuals affected with Neurodevelopmental Disorder With Cerebellar Hypoplasia And Spasticity and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. -
