| Fetal anomalies v1.476 | COL10A1 |
Zornitza Stark changed review comment from: Note: Gene reviews also notes severe lethal phenotypes in recessive inheritance where parents were only mildly affected, however only 2 unrelated families reported to date (PMID: 31633898). Both haploinsufficiency and dominant-negative mechanisms have been suggested to cause disease (OMIM, PMID: 15880705, PMID: 31633898). “Pathogenic variants in COL10A1 are clustered in the C-terminal non-collagenous (NC1) domain, which contains motifs required for normal assembly of the collagen trimer. Both missense and truncating (frameshift and nonsense) variants in COL10A1 cause collagen X protein misfolding during protein synthesis, resulting in a failure of trimerization and aggregation within the endoplasmic reticulum (ER) of hypertrophic chondrocytes. Resultant ER stress, activation of the unfolded protein response, and reduced levels of functional type X collagen in the growth plate cause chondrodysplasia and development of the SMCD phenotype [Rajpar et al 2009].” -> from Gene Reviews (PMID: 31633898). Some pathogenic missense also reported in the N-terminal signal peptide (Decipher), however please note that to date, no Gly-X-Y substitutions in the collagen triple helix repeats have yet been reported, pathogenic or otherwise.; to: Note: Gene reviews also notes severe lethal phenotypes in recessive inheritance where parents were only mildly affected, however only 2 unrelated families reported to date (PMID: 31633898).

Some pathogenic missense also reported in the N-terminal signal peptide (Decipher). Note that unlike with other collagens, Gly-X-Y substitutions in the collagen triple helix repeats are very rarely reported as disease-causing, and may result in a milder phenotype (PMID 31348255; 25542771). These should be interpreted with caution. |
