Genes affected
SEC16B (HGNC:30301): (SEC16 homolog B, endoplasmic reticulum export factor) SEC16B is a mammalian homolog of S. cerevisiae Sec16 that is required for organization of transitional endoplasmic reticulum (ER) sites and protein export (Bhattacharyya and Glick, 2007 [PubMed 17192411]).[supplied by OMIM, Jun 2009]
CRYZL2P-SEC16B (HGNC:53757): (CRYZL2P-SEC16B readthrough) This locus represents naturally occurring read-through transcription between the neighboring CRYZL2P (crystallin zeta like 2 pseudogene) and SEC16B (SEC16 homolog B, endoplasmic reticulum export factor) genes on chromosome 1. The readthrough transcript encodes a protein that shares sequence identity with the downstream gene product. [provided by RefSeq, Oct 2017]
