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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2023The c.944C>T (p.S315F) alteration is located in exon 8 (coding exon 8) of the INTS8 gene. This alteration results from a C to T substitution at nucleotide position 944, causing the serine (S) at amino acid position 315 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
