Genes affected

SIAE (HGNC:18187): (sialic acid acetylesterase) This gene encodes an enzyme which removes 9-O-acetylation modifications from sialic acids. Mutations in this gene are associated with susceptibility to autoimmune disease 6. Multiple transcript variants encoding different isoforms, found either in the cytosol or in the lysosome, have been found for this gene.[provided by RefSeq, Feb 2011]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant, c.1512_1514del, results in the deletion of 1 amino acid(s) of the SIAE protein (p.Pro505del), but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SIAE-related conditions. ClinVar contains an entry for this variant (Variation ID: 1362367). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
