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]

CNN3-DT (HGNC:54176): (CNN3 divergent transcript)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.804 is higher than 0.05.
