Genes affected
NDNF (HGNC:26256): (neuron derived neurotrophic factor) Predicted to enable heparin binding activity. Involved in several processes, including cellular response to hypoxia; negative regulation of apoptotic process; and nitric oxide mediated signal transduction. Located in extracellular space. Implicated in hypogonadotropic hypogonadism. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 19, 2023The c.923C>T (p.T308M) alteration is located in exon 4 (coding exon 3) of the NDNF gene. This alteration results from a C to T substitution at nucleotide position 923, causing the threonine (T) at amino acid position 308 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
