Additional glycopeptides enriched in individuals with bipolar depression were derived from CA2D1 (3 glycopeptides with 3 glycan compositions across 1 site), tyrosine-protein phosphatase non-receptor type substrate 1 (SHPS1; 3 glycopeptides with 3 glycan compositions across 2 sites), ceruloplasmin (CERU; 2 glycopeptides with 2 glycan compositions across 2 sites), leukocyte surface antigen CD47 (2 glycopeptides with 2 glycan compositions across 1 site) and brevican core protein (PGCB; 2 glycopeptides with 2 glycan compositions across 1 site). The gene discussed is SIRPA; the disease is bipolar disorder.
