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.

GOLGA7B (HGNC:31668): (golgin A7 family member B) Enables enzyme binding activity. Predicted to be involved in peptidyl-L-cysteine S-palmitoylation and protein targeting to membrane. Predicted to be located in Golgi membrane. Predicted to be part of palmitoyltransferase complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.1828G>A (p.G610S) alteration is located in exon 15 (coding exon 15) of the CRTAC1 gene. This alteration results from a G to A substitution at nucleotide position 1828, causing the glycine (G) at amino acid position 610 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
