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.-12C>T variant (rs571429116), to our knowledge, is not reported in the medical literature or gene specific databases. This variant is found in the general population with an overall allele frequency of 0.006% (2/30934 alleles) in the Genome Aggregation Database. This variant occurs in the 5' untranslated region at a nucleotide that is moderately conserved, but computational analyses (NetStart 1.0, Promoter 2.0) predict that this variant does not significantly alter transcription or translation initiation. Based on available information, this variant is considered to be likely benign. -
