Genes affected
CASC3 (HGNC:17040): (CASC3 exon junction complex subunit) The product of this gene is a core component of the exon junction complex (EJC), a protein complex that is deposited on spliced mRNAs at exon-exon junctions and functions in nonsense-mediated mRNA decay (NMD). The encoded protein binds RNA and interacts with two other EJC core components. It is predominantly located in the cytoplasm, but shuttles into the nucleus where it localizes to nuclear speckles.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.1012C>T (p.R338W) alteration is located in exon 7 (coding exon 7) of the CASC3 gene. This alteration results from a C to T substitution at nucleotide position 1012, causing the arginine (R) at amino acid position 338 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
