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]

CACTIN-AS1 (HGNC:31391): (CACTIN antisense RNA 1)

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.06555599).
