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.1404T>G (p.I468M) alteration is located in exon 8 (coding exon 8) of the CRNKL1 gene. This alteration results from a T to G substitution at nucleotide position 1404, causing the isoleucine (I) at amino acid position 468 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
