Genes affected

ARSL (HGNC:719): (arylsulfatase L) Arylsulfatase E is a member of the sulfatase family. It is glycosylated postranslationally and localized to the golgi apparatus. Sulfatases are essential for the correct composition of bone and cartilage matrix. X-linked chondrodysplasia punctata, a disease characterized by abnormalities in cartilage and bone development, has been linked to mutations in this gene. Alternative splicing results in multiple transcript variants. A pseudogene related to this gene is located on the Y chromosome. [provided by RefSeq, Sep 2013]

This sequence change creates a premature translational stop signal (p.Trp581*) in the ARSE gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 9 amino acid(s) of the ARSE protein. This variant is present in population databases (rs80338714, gnomAD 0.002%). This premature translational stop signal has been observed in individuals with chondrodysplasia punctata (PMID: 9863597, 12567415). ClinVar contains an entry for this variant (Variation ID: 11529). For these reasons, this variant has been classified as Pathogenic. -
