Potential risk genes for primary Sjogren's syndrome from a meta-analysis by linear regression and random forest classification

Primary Sjogren's syndrome(psS)is one of the most widespread autoimmune diseases with unknown origin,characterized by a lymphocytic infiltrate of the exocrine glands and the production of anti-SSA/Ro and anti-SSB/La antibodies that cause dysfunction and destruction mainly of salivary and lachrymal glands,leading to dry eyes and dry mouth.In the absence of a standardized evidence-based screening tool to decide which patients with dry eye must be referred for study of this pathology.
