Genes affected

SEC31B (HGNC:23197): (SEC31 homolog B, COPII coat complex component) This gene encodes a protein of unknown function. The protein has moderate similarity to rat VAP1 protein which is an endosomal membrane-associated protein, containing a putative Ca2+/calmodulin-dependent kinase II phosphorylation site.
