Description

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. This variant has not been reported in the literature in individuals affected with CNGB1-related conditions. This variant results in a copy number gain of the genomic region encompassing exon(s) 27 of the CNGB1 gene. While the exact position of this variant cannot be determined from the data, sub-genic copy number gains are generally in tandem (PMID: 25640679). This variant is predicted to be out-of-frame, and may result in an absent or disrupted protein product. Loss-of-function variants in CNGB1 are known to be pathogenic (PMID: 15557452, 24043777).
