Genes affected

COL10A1 (HGNC:2185): (collagen type X alpha 1 chain) This gene encodes the alpha chain of type X collagen, a short chain collagen expressed by hypertrophic chondrocytes during endochondral ossification. Unlike type VIII collagen, the other short chain collagen, type X collagen is a homotrimer. Mutations in this gene are associated with Schmid type metaphyseal chondrodysplasia (SMCD) and Japanese type spondylometaphyseal dysplasia (SMD). [provided by RefSeq, Jul 2008]

NT5DC1 (HGNC:21556): (5'-nucleotidase domain containing 1) While the exact function of the protein encoded by this gene is not known, it belongs to the 5'(3')-deoxyribonucleotidase family. [provided by RefSeq, May 2010]

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.
