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]

ARSL (HGNC:):

ACMG classification

Verdict is Pathogenic. Variant got 14 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.982
• PP5: Variant X-2953224-C-T is Pathogenic according to our data. Variant chrX-2953224-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 11523.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chrX-2953224-C-T is described in Lovd as [Pathogenic].
