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]

SIAE Gene-Disease associations (from GenCC):

• autoimmune disease, susceptibility to, 6

  Inheritance: Unknown Classification: LIMITED Submitted by: Laboratory for Molecular Medicine, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
