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]

Ambry Genetics

Jul 27, 2023

The c.1724T>C (p.M575T) alteration is located in exon 11 (coding exon 11) of the CRNKL1 gene. This alteration results from a T to C substitution at nucleotide position 1724, causing the methionine (M) at amino acid position 575 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
