Genes affected
ALG14 (HGNC:28287): (ALG14 UDP-N-acetylglucosaminyltransferase subunit) This gene is a member of the glycosyltransferase 1 family. The encoded protein and ALG13 are thought to be subunits of UDP-GlcNAc transferase, which catalyzes the first two committed steps in endoplasmic reticulum N-linked glycosylation. Mutations in this gene have been linked to congenital myasthenic syndrome (CMSWTA). Alternatively spliced transcript variants have been identified. [provided by RefSeq, Mar 2015]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. ClinVar contains an entry for this variant (Variation ID: 183014). This premature translational stop signal has been observed in individual(s) with clinical features ALG14-related conditions (PMID: 23404334). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs367570129, gnomAD 0.008%). This sequence change creates a premature translational stop signal (p.Arg104*) in the ALG14 gene. It is expected to result in an absent or disrupted protein product. However, the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in ALG14 cause disease. -
