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]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.974
• PP5: Variant X-2949425-C-G is Pathogenic according to our data. Variant chrX-2949425-C-G is described in ClinVar as [Pathogenic]. Clinvar id is 11526.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chrX-2949425-C-G is described in Lovd as [Pathogenic]. Variant chrX-2949425-C-G is described in Lovd as [Likely_pathogenic].
