Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001080453.3(INTS1):ā€‹c.6427A>Cā€‹(p.Asn2143His) variant causes a missense change. The variant allele was found at a frequency of 0.0000132 in 1,442,398 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N2143K) has been classified as Uncertain significance.

Genes affected
INTS1 (HGNC:24555): (integrator complex subunit 1) INTS1 is a subunit of the Integrator complex, which associates with the C-terminal domain of RNA polymerase II large subunit (POLR2A; MIM 180660) and mediates 3-prime end processing of small nuclear RNAs U1 (RNU1; MIM 180680) and U2 (RNU2; MIM 180690) (Baillat et al., 2005 [PubMed 16239144]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2024The c.6427A>C (p.N2143H) alteration is located in exon 47 (coding exon 46) of the INTS1 gene. This alteration results from a A to C substitution at nucleotide position 6427, causing the asparagine (N) at amino acid position 2143 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
