Variant 19-3612369-T-G details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_001080543.2(CACTIN):c.1831A>C(p.Lys611Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000275 in 1,454,406 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K611R) has been classified as Uncertain significance.

Genes affected

CACTIN (HGNC:29938): (cactin, spliceosome C complex subunit) Enables RNA binding activity. Involved in several processes, including cellular response to cytokine stimulus; negative regulation of cytokine production; and negative regulation of signal transduction. Located in cytosol and nuclear speck. Part of catalytic step 2 spliceosome. [provided by Alliance of Genome Resources, Apr 2022]

The c.1831A>C (p.K611Q) alteration is located in exon 10 (coding exon 10) of the CACTIN gene. This alteration results from a A to C substitution at nucleotide position 1831, causing the lysine (K) at amino acid position 611 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
