Genes affected
NTF4 (HGNC:8024): (neurotrophin 4) This gene is a member of a family of neurotrophic factors, neurotrophins, that control survival and differentiation of mammalian neurons. The expression of this gene is ubiquitous and less influenced by environmental signals. While knock-outs of other neurotrophins including nerve growth factor, brain-derived neurotrophic factor, and neurotrophin 3 prove lethal during early postnatal development, NTF5-deficient mice only show minor cellular deficits and develop normally to adulthood.

The heterozygous p.Ala88Val variant in NTF4 has been identified in at least 13 individuals with glaucoma and at least 19 individuals without glaucoma (PMID: 19765683, 20215012, 20463313), but has also been identified in >2% of South Asian chromosomes and 8 homozygotes by ExAC (http://gnomad.broadinstitute.org/). In summary, although additional studies are required to fully establish its clinical significance, this variant meets criteria to be classified as likely benign for autosomal dominant primary open angle glaucoma. -
