Disease relevance of CHRNE

A frameshifting 7 bp deletion (epsilon553del7) in exon 7 of CHRNE encoding the acetylcholine receptor epsilon subunit, observed in seven congenital myasthenic syndrome patients, enhances expression of an aberrantly spliced transcript that skips the preceding 101 bp exon 6 [1].

High impact information on CHRNE

To recapitulate the aberrant splicing, we cloned the entire CHRNE spanning 12 exons and 11 introns and expressed it in COS cells [1].
Inhibition of protein synthesis and of nonsense-mediated mRNA decay (NMD) by anisomycin shows that even wild-type CHRNE produces an exon 6-skipped transcript, and that even epsilon553del7-CHRNE yields a normally spliced transcript [1].

In contrast, the corresponding amino acid substitution in the cytoplasmic loop of the AChR epsilon (CHRNE E376K) as well as a recently reported CMS mutation affecting this domain (CHRNE N436del) had no impact on cluster formation [3].
