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]

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: ARSL c.1189G>A (p.Gly397Arg) results in a non-conservative amino acid change located in the N-terminal domain (IPR000917) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0006 in 203935 control chromosomes, including 42 hemizygotes. The occurrence in several hemizygotes suggests that this variant is likely not associated with a high penetrance, severe, early onset disease phenotype in hemizygous state. To our knowledge, no occurrence of c.1189G>A in individuals affected with Chondrodysplasia Punctata 1, X-Linked Recessive and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 522724). Based on the evidence outlined above, the variant was classified as likely benign. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
