Genes affected

ALG11 (HGNC:32456): (ALG11 alpha-1,2-mannosyltransferase) This gene encodes a GDP-Man:Man3GlcNAc2-PP-dolichol-alpha1,2-mannosyltransferase which is localized to the cytosolic side of the endoplasmic reticulum (ER) and catalyzes the transfer of the fourth and fifth mannose residue from GDP-mannose (GDP-Man) to Man3GlcNAc2-PP-dolichol and Man4GlcNAc2-PP-dolichol resulting in the production of Man5GlcNAc2-PP-dolichol. Mutations in this gene are associated with congenital disorder of glycosylation type Ip (CDGIP). This gene overlaps but is distinct from the UTP14, U3 small nucleolar ribonucleoprotein, homolog C (yeast) gene. A pseudogene of the GDP-Man:Man3GlcNAc2-PP-dolichol-alpha1,2-mannosyltransferase has been identified on chromosome 19. [provided by RefSeq, Aug 2010]

UTP14C (HGNC:20321): (UTP14C small subunit processome component) Predicted to be involved in several processes, including meiotic cell cycle; rRNA processing; and spermatogenesis. Located in cytosol and nucleolus. [provided by Alliance of Genome Resources, Apr 2022]

The c.1146G>T (p.K382N) alteration is located in exon 3 (coding exon 3) of the ALG11 gene. This alteration results from a G to T substitution at nucleotide position 1146, causing the lysine (K) at amino acid position 382 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
