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.2513A>G (p.H838R) alteration is located in exon 15 (coding exon 15) of the CRNKL1 gene. This alteration results from a A to G substitution at nucleotide position 2513, causing the histidine (H) at amino acid position 838 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
