Similar deletions of this genomic region have been reported in an individual with symptoms consistent with a mild form of Cowden syndrome (PMID: 18456716), as well as in an individual with juvenile polyposis syndrome (PMID: 16287957). This variant is a gross deletion of the genomic region encompassing the promoter and exon 1 of the PTEN gene, which includes the initiator codon. The 5' end of this event is unknown as it extends beyond the assayed region for this gene and therefore may encompass additional genes.

Comment:

For these reasons, this variant has been classified as Pathogenic. Similar deletions of this genomic region have been reported in an individual with symptoms consistent with a mild form of Cowden syndrome (PMID: 18456716), as well as in an individual with juvenile polyposis syndrome (PMID: 16287957).
