Genes affected

NGF (HGNC:7808): (nerve growth factor) This gene is a member of the NGF-beta family and encodes a secreted protein which homodimerizes and is incorporated into a larger complex. This protein has nerve growth stimulating activity and the complex is involved in the regulation of growth and the differentiation of sympathetic and certain sensory neurons. Mutations in this gene have been associated with hereditary sensory and autonomic neuropathy, type 5 (HSAN5), and dysregulation of this gene's expression is associated with allergic rhinitis.

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬† is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 456632). This variant has not been reported in the literature in individuals affected with NGF-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 124 of the NGF protein (p.Ser124Phe). -
