Genes affected

INTS7 (HGNC:24484): (integrator complex subunit 7) This gene encodes a subunit of the integrator complex. The integrator complex associates with the C-terminal domain of RNA polymerase II and mediates 3'-end processing of the small nuclear RNAs U1 and U2. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2010]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.2408G>A (p.S803N) alteration is located in exon 18 (coding exon 18) of the INTS7 gene. This alteration results from a G to A substitution at nucleotide position 2408, causing the serine (S) at amino acid position 803 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
