Genes affected

CSRNP1 (HGNC:14300): (cysteine and serine rich nuclear protein 1) This gene encodes a protein that localizes to the nucleus and expression of this gene is induced in response to elevated levels of axin. The Wnt signalling pathway, which is negatively regulated by axin, is important in axis formation in early development and impaired regulation of this signalling pathway is often involved in tumors. A decreased level of expression of this gene in tumors compared to the level of expression in their corresponding normal tissues suggests that this gene product has a tumor suppressor function. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

The c.1724T>C (p.F575S) alteration is located in exon 5 (coding exon 4) of the CSRNP1 gene. This alteration results from a T to C substitution at nucleotide position 1724, causing the phenylalanine (F) at amino acid position 575 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
