Genes affected

NRTN (HGNC:8007): (neurturin) This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. The encoded preproprotein is proteolytically processed to generate the mature protein. This protein signals through the RET receptor tyrosine kinase and a GPI-linked coreceptor, and promotes survival of neuronal populations. A neurturin mutation has been described in a family with Hirschsprung Disease. [provided by RefSeq, Aug 2016]

The c.481G>C (p.A161P) alteration is located in exon 2 (coding exon 2) of the NRTN gene. This alteration results from a G to C substitution at nucleotide position 481, causing the alanine (A) at amino acid position 161 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
