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.

Ambry Genetics

Jun 16, 2022

The c.1300G>A (p.V434I) alteration is located in exon 10 (coding exon 10) of the CRTAC1 gene. This alteration results from a G to A substitution at nucleotide position 1300, causing the valine (V) at amino acid position 434 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
