Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the ANTXR2 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Disease: DISEASE: Hyaline fibromatosis syndrome (HFS) [MIM:228600]: An autosomal recessive syndrome characterized by abnormal growth of hyalinized fibrous tissue usually affecting subcutaneous regions on the scalp, ears, neck, face, hands, and feet. The lesions appear as pearly papules or fleshy nodules. Additional features include gingival hypertrophy, progressive joint contractures resulting in severe limitation of mobility, osteopenia, and osteoporosis. Disease severity is variable. Some individuals manifest symptoms in infancy and have additional visceral or systemic involvement. Hyaline deposits in multiple organs, recurrent infections and intractable diarrhea often lead to early death. Surviving children may suffer from severely reduced mobility due to joint contractures. Other patients have later onset of a milder disorder affecting only the face and digits. {ECO:0000269|PubMed:12973667, ECO:0000269|PubMed:14508707, ECO:0000269|PubMed:15725249}. Note=The disease is caused by mutations affecting the gene represented in this entry.
