Genes affected

FAM89B (HGNC:16708): (family with sequence similarity 89 member B) Predicted to enable transcription corepressor binding activity. Predicted to be involved in establishment of cell polarity; negative regulation of transmembrane receptor protein serine/threonine kinase signaling pathway; and positive regulation of cell migration. Predicted to be active in cytoplasm and lamellipodium. [provided by Alliance of Genome Resources, Apr 2022]

ZNRD2 (HGNC:11328): (zinc ribbon domain containing 2) This antigen is recognized by a subset of anti-centromere antibodies from patients with scleroderma and/or Sjogren's syndrome. Subcellular localization has not yet been established. [provided by RefSeq, Jul 2008]

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. -
