Comment:

For these reasons, this variant has been classified as Pathogenic. A similar whole gene deletion has been observed in individual(s) with macular corneal dystrophy (PMID: 11017086). A gross deletion of the genomic region encompassing the full coding sequence of the CHST6 gene has been identified. Loss-of-function variants in CHST6 are known to be pathogenic (PMID: 14609920, 14735064). The boundaries of this event are unknown as they extend beyond the assayed region for this gene and therefore may encompass additional genes.
