Invitae RCV001032770 SCV001196077 uncertain significance PTEN hamartoma tumor syndrome 2019-04-12 criteria provided, single submitter clinical testing This variant results in a copy number gain of the genomic region encompassing exon 1 of the PTEN gene. The 5' end of this event is unknown as it extends beyond the assayed region for this gene and therefore may encompass additional genes. The 3' boundary is likely confined to intron 1 of the PTEN gene, which includes the initiator codon. As the precise location of this event is unknown, it may be in tandem or it may be located elsewhere in the genome. Duplications of the promoter region and exon 1 of the PTEN gene have been reported in individuals affected with Cowden or Cowden-like syndrome (PMID: 25669429, 22595938). In one of these individuals, the duplication has been reported to be de novo (PMID: 22595938). However, there is uncertainty as to how this duplication compares to the duplications reported in the literature. 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.
