Genes affected
GDF5 (HGNC:4220): (growth differentiation factor 5) 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 the development of numerous tissue and cell types, including cartilage, joints, brown fat, teeth, and the growth of neuronal axons and dendrites. Mutations in this gene are associated with acromesomelic dysplasia, brachydactyly, chondrodysplasia, multiple synostoses syndrome, proximal symphalangism, and susceptibility to osteoarthritis.

This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 441 of the GDF5 protein (p.Leu441Pro). For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects GDF5 function (PMID: 16127465, 21976273). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt GDF5 protein function. ClinVar contains an entry for this variant (Variation ID: 8381). This variant is also known as L60P. This missense change has been observed in individuals with GDF5-related conditions (PMID: 12121354, 16014698). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). -
