Genes affected
CRTAC1 (HGNC:14882): (cartilage acidic protein 1) This gene encodes a glycosylated extracellular matrix protein that is found in the interterritorial matrix of articular deep zone cartilage. This protein is used as a marker to distinguish chondrocytes from osteoblasts and mesenchymal stem cells in culture. The presence of FG-GAP motifs and an RGD integrin-binding motif suggests that this protein may be involved in cell-cell or cell-matrix interactions. Copy number alterations in this gene have been observed in neurofibromatosis type 1-associated glomus tumors. Alternative splicing results in multiple transcript variants.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 08, 2023The c.1750T>C (p.Y584H) alteration is located in exon 14 (coding exon 14) of the CRTAC1 gene. This alteration results from a T to C substitution at nucleotide position 1750, causing the tyrosine (Y) at amino acid position 584 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
