Genes affected

CRNKL1 (HGNC:15762): (crooked neck pre-mRNA splicing factor 1) The crooked neck (crn) gene of Drosophila is essential for embryogenesis and is thought to be involved in cell cycle progression and pre-mRNA splicing. A protein encoded by this human locus has been found to localize to pre-mRNA splicing complexes in the nucleus and is necessary for pre-mRNA splicing. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2013]

The c.2114G>A (p.R705Q) alteration is located in exon 13 (coding exon 13) of the CRNKL1 gene. This alteration results from a G to A substitution at nucleotide position 2114, causing the arginine (R) at amino acid position 705 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
