Genes affected
C16orf89 (HGNC:28687): (chromosome 16 open reading frame 89) This gene is expressed predominantly in the thyroid. Based on expression patterns similar to thyroid transcription factors and proteins, this gene may function in the development and function of the thyroid. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]
ALG1 (HGNC:18294): (ALG1 chitobiosyldiphosphodolichol beta-mannosyltransferase) The enzyme encoded by this gene catalyzes the first mannosylation step in the biosynthesis of lipid-linked oligosaccharides. This gene is mutated in congenital disorder of glycosylation type Ik. [provided by RefSeq, Dec 2008]
