Genes affected

SPCS1 (HGNC:23401): (signal peptidase complex subunit 1) Predicted to enable peptidase activity and ribosome binding activity. Involved in viral protein processing and virion assembly. Is integral component of endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]

SPCS1 links:

GLT8D1 (HGNC:24870): (glycosyltransferase 8 domain containing 1) This gene encodes a member of the glycosyltransferase family. The specific function of this protein has not been determined. Alternative splicing results in multiple transcript variants of this gene [provided by RefSeq, May 2013]

GLT8D1 Gene-Disease associations (from GenCC):
