Genes affected
NTF3 (HGNC:8023): (neurotrophin 3) The protein encoded by this gene is a member of the neurotrophin family, that controls survival and differentiation of mammalian neurons. This protein is closely related to both nerve growth factor and brain-derived neurotrophic factor. It may be involved in the maintenance of the adult nervous system, and may affect development of neurons in the embryo when it is expressed in human placenta. NTF3-deficient mice generated by gene targeting display severe movement defects of the limbs. The mature peptide of this protein is identical in all mammals examined including human, pig, rat and mouse. [provided by RefSeq, Jul 2008]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.437G>T (p.R146L) alteration is located in exon 1 (coding exon 1) of the NTF3 gene. This alteration results from a G to T substitution at nucleotide position 437, causing the arginine (R) at amino acid position 146 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
