Genes affected

EDC3 (HGNC:26114): (enhancer of mRNA decapping 3) This gene encodes a protein that is important in mRNA degradation. The encoded protein is a component of a decapping complex that promotes efficient removal of the monomethylguanosine (m7G) cap from mRNAs, as part of the 5' to 3' mRNA decay pathway. Mutations in this gene have been identified in human patients with an autosomal recessive form of intellectual disability. [provided by RefSeq, May 2017]

EDC3 links:

CLK3 (HGNC:2071): (CDC like kinase 3) This gene encodes a protein belonging to the serine/threonine type protein kinase family. This protein is a nuclear dual-specificity kinase that regulates the intranuclear distribution of the serine/arginine-rich (SR) family of splicing factors. Two transcript variants encoding different isoforms have been found for this gene. Related pseudogenes are located on chromosomes 1 and 9. [provided by RefSeq, Jul 2008]

The c.861T>A (p.H287Q) alteration is located in exon 8 (coding exon 4) of the EDC3 gene. This alteration results from a T to A substitution at nucleotide position 861, causing the histidine (H) at amino acid position 287 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
