The current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in SKI cause disease. The boundaries of this event are unknown as they extend beyond the assayed region for this gene and therefore may encompass additional genes. Isolated whole-gene deletions of SKI have not been reported in the literature. However, larger copy number events that include this gene have been reported (PMID: 23892090, 31602316).

A gross deletion of the genomic region encompassing the full coding sequence of the SKI gene has been identified.

Isolated whole-gene deletions of SKI have not been reported in the literature. However, larger copy number events that include this gene have been reported (PMID: 23892090, 31602316).
