Genes affected

NENF (HGNC:30384): (neudesin neurotrophic factor) This gene encodes a neurotrophic factor that may play a role in neuron differentiation and development. A pseudogene of this gene is found on chromosome 12. Alternate splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jan 2009]

Collection Method: clinical testing

The c.31C>T (p.R11W) alteration is located in exon 1 (coding exon 1) of the NENF gene. This alteration results from a C to T substitution at nucleotide position 31, causing the arginine (R) at amino acid position 11 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
