Genes affected
CSAG1 (HGNC:24294): (chondrosarcoma associated gene 1) This gene encodes a member of a family of tumor antigens. The protein is expressed in chondrosarcomas, but may also be expressed in normal tissues such as testis. Alternative splicing of this gene results in two transcript variants encoding the same protein. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2022The c.200C>T (p.P67L) alteration is located in exon 5 (coding exon 3) of the CSAG1 gene. This alteration results from a C to T substitution at nucleotide position 200, causing the proline (P) at amino acid position 67 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
