Invitae | RCV000817289 | SCV000957839 | pathogenic | PTEN hamartoma tumor syndrome | 2018-09-17 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing the promoter as well as exons 1 to 2 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. The 3' boundary is likely confined to intron 2 of the PTEN gene. This is expected to result in an absent or disrupted protein product. A similar deletion of exons 1 and 2 has been observed in an individual with Cowden syndrome (PMID: 25669429) as well as an individual with pediatric PTEN hamartoma tumor syndrome (Invitae). Loss-of-function variants in PTEN are known to be pathogenic (PMID: 9467011, 21194675). For these reasons, this variant has been classified as Pathogenic. |
