Three of these regions contained genes putatively related to asthma or atopy: collagen type XXIX alpha 1 (COL29A1, also known as COL6A5, a new member of the collagen family [19]), mitogen-activated protein kinase kinase kinase 5 (MAP3K5, also known as apoptosis signal-regulating kinase 1 (ASK1)), collagen type XVIII alpha 1 (COL18A1) and solute carrier family 19 member 1 (SLC19A1). The gene discussed is COL18A1; the disease is asthma.
