Invitae | RCV001044724 | SCV001208537 | likely pathogenic | Congenital myasthenic syndrome 4A | 2019-12-30 | criteria provided, single submitter | clinical testing | This variant, c.1297_1314dup, results in the insertion of 6 amino acid(s) to the CHRNE protein (p.Ser433_Glu438dup), but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with autosomal recessive congenital myasthenic syndrome (PMID: 9539130). It has also been observed to segregate with disease in related individuals. This variant is also known as 1254ins18 in the literature. This variant has been reported to affect CHRNE protein function (PMID: 9539130). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. |
