ClinVar

This is a list of variants' phenotypes submitted to ClinVar and linked to the ARSL gene.

• not provided (4 variants)
• X-linked chondrodysplasia punctata 1 (1 variants)

Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the ARSL 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.

• Function: FUNCTION: May be essential for the correct composition of cartilage and bone matrix during development. Has no activity toward steroid sulfates.
• Disease: DISEASE: Chondrodysplasia punctata 1, X-linked recessive (CDPX1) [MIM:302950]: A clinically and genetically heterogeneous disorder characterized by punctiform calcification of the bones. CDPX1 is a congenital defect of bone and cartilage development characterized by aberrant bone mineralization, severe underdevelopment of nasal cartilage, and distal phalangeal hypoplasia. This disease can also be induced by inhibition with the drug warfarin. {ECO:0000269|PubMed:12567415, ECO:0000269|PubMed:7720070, ECO:0000269|PubMed:9409863}. Note=The disease is caused by mutations affecting the gene represented in this entry.
