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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 22, 2023The c.2986G>C (p.G996R) alteration is located in exon 24 (coding exon 23) of the SEC16B gene. This alteration results from a G to C substitution at nucleotide position 2986, causing the glycine (G) at amino acid position 996 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
