Variant summary

Our verdict is Likely pathogenic. The variant received 9 ACMG points: 9P and 0B. PM2 PM5 PP3_Strong PP5

The NM_000047.3(ARSL):​c.332G>C​(p.Arg111Pro) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R111C) has been classified as Likely pathogenic.

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

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chrX-2953242-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 427005.Status of the report is criteria_provided_single_submitter, 1 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.959
• PP5: Variant X-2953241-C-G is Pathogenic according to our data. Variant chrX-2953241-C-G is described in ClinVar as Pathogenic. ClinVar VariationId is 11524.Status of the report is no_assertion_criteria_provided, 0 stars.
