Genes affected
GDF2 (HGNC:4217): (growth differentiation factor 2) This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. This protein regulates cartilage and bone development, angiogenesis and differentiation of cholinergic central nervous system neurons. Mutations in this gene are associated with hereditary hemorrhagic telangiectasia. [provided by RefSeq, Jul 2016]

The GDF2 c.-19G>A variant (rs782261249), to our knowledge, is not reported in the medical literature or gene specific databases. This variant is only observed on one allele in the Genome Aggregation Database (v2.1.1), indicating it is not a common polymorphism. This variant is located in the 5' untranslated region and creates a novel protein translation start codon, that if utilized may cause a frameshift. However, given the lack of clinical and functional data, the significance of this variant is uncertain at this time. -
