Genes affected

ANXA11 (HGNC:535): (annexin A11) This gene encodes a member of the annexin family, a group of calcium-dependent phospholipid-binding proteins. Annexins have unique N-terminal domains and conserved C-terminal domains, which contain calcium-dependent phospholipid-binding sites. The encoded protein is a 56-kD antigen recognized by sera from patients with various autoimmune diseases. Several transcript variants encoding two different isoforms have been identified.

Collection Method: clinical testing

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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with ANXA11-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces aspartic acid with histidine at codon 484 of the ANXA11 protein (p.Asp484His). The aspartic acid residue is highly conserved and there is a moderate physicochemical difference between aspartic acid and histidine. -
