ClinGen PTEN Variant Curation Expert Panel RCV000233564 SCV000863474 likely benign PTEN hamartoma tumor syndrome 2018-04-06 reviewed by expert panel curation PTEN c.-1142C>T (NC_000010.10:g.89623084C>T) meets criteria to be classified as likely benign for PTEN Hamartoma Tumor syndrome in an autosomal dominant manner using modified ACMG criteria (PMID 30311380). Please see a summary of the rules and criteria codes in the "PTEN ACMG Specifications Summary" document (assertion method column). BS1: Allele frequency of 0.0049 (0.49%, 8/1622 alleles) in the East Asian subpopulation of the gnomAD cohort. (PMID 27535533) BP2: Observed in trans with a pathogenic or likely pathogenic PTEN variant, at least three observations in cis and/or phase unknown with different pathogenic/likely pathogenic PTEN variants.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000590028 SCV000696527 likely benign not provided 2017-01-20 criteria provided, single submitter clinical testing Variant summary: The PTEN variant c.-1142C>T (also known as c.-1143C>T) located in the 5' UTR region of PTEN causes an alteration of a non-conserved nucleotide. The variant of interest was observed in the 1000 Gs control population with an allele frequency of 12/5044 (1/420, 1 homozygote), predominantly in the East Asian cohort, 8/1008 (1/125, 1 homozygote), which exceeds the estimated maximal expected allele frequency for a pathogenic PTEN variant of 1/158730. Therefore, suggesting this variant is likely a benign polymorphism for in population(s) of East Asian origin. However, these observations do need to be cautiously considered due to the PTEN pseudogene possibly being captured. A functional study, Ohsaka_2010, found the variant not to affect luciferase activity, although they do state the outcome is cell type dependent. In addition, multiple clinical diagnostic laboratories classified this variant as "likely benign" or "uncertain significance." Therefore, the variant of interest has been classified as "likely benign."
