Alport Syndrome 2, Autosomal Recessive, also known as ats2, is related to alport syndrome 3b, autosomal recessive and autosomal recessive alport syndrome. An important gene associated with Alport Syndrome 2, Autosomal Recessive is COL4A4 (Collagen Type IV Alpha 4 Chain), and among its related pathways/superpathways are Cytoskeleton remodeling Regulation of actin cytoskeleton by Rho GTPases and Non-integrin membrane-ECM interactions. Affiliated tissues include eye and kidney, and related phenotypes are hypertension and hearing impairment
