Description

A gross deletion of the genomic region encompassing the full coding sequence of the KANK1 gene has been identified. The current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in KANK1 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. A similar copy number variant has been observed in individual(s) with cerebral palsy (PMID: 25817843). 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.
