RCV003041145 | SCV003347326 | uncertain significance | Congenital myotonia, autosomal recessive form; Congenital myotonia, autosomal dominant form | 2023-08-11 | criteria provided, single submitter | clinical testing | This variant, c.984_989del, results in the deletion of 2 amino acid(s) of the CLCN1 protein (p.Ile329_Thr330del), but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CLCN1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2133862). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. |
