Genes affected

LAMB4 (HGNC:6491): (laminin subunit beta 4) Predicted to be an extracellular matrix structural constituent. Predicted to be involved in several processes, including basement membrane assembly; cell migration; and substrate adhesion-dependent cell spreading. Predicted to be located in basement membrane; extracellular region; and membrane. Predicted to be part of laminin complex. [provided by Alliance of Genome Resources, Apr 2022]
