Genes affected

GDNF (HGNC:4232): (glial cell derived neurotrophic factor) 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. The recombinant form of this protein, a highly conserved neurotrophic factor, was shown to promote the survival and differentiation of dopaminergic neurons in culture, and was able to prevent apoptosis of motor neurons induced by axotomy. This protein is a ligand for the product of the RET (rearranged during transfection) protooncogene. Mutations in this gene may be associated with Hirschsprung disease and Tourette syndrome. This gene encodes multiple protein isoforms that may undergo similar proteolytic processing. [provided by RefSeq, Aug 2016]

Variant summary: GDNF c.633C>G (p.Ile211Met) results in a conservative amino acid change located in the Transforming growth factor-beta, C-terminal domain (IPR001839) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 9.9e-05 in 251428 control chromosomes, predominantly at a frequency of 0.00022 within the Non-Finnish European subpopulation in the gnomAD database. This frequency is not significantly higher than estimated for a pathogenic variant in GDNF causing Hirschsprung Disease, Susceptibility To, 3, allowing no conclusion about variant significance. c.633C>G has been reported in the literature in individuals affected with Hirschsprung Disease and Kidney and/or genitourinary disorder (example, Martucciello_2000, Rasouly_2019), without strong evidence for causality. These report(s) do not provide unequivocal conclusions about association of the variant with Hirschsprung Disease, Susceptibility To, 3. One publication reports experimental evidence evaluating an impact on protein function, however, does not allow convincing conclusions about the variant effect (Eketjall_2002). The following publications have been ascertained in the context of this evaluation (PMID: 11823451, 10917288, 26489027, 30476936). ClinVar contains an entry for this variant (Variation ID: 8761). Based on the evidence outlined above, the variant was classified as uncertain significance. -
