Reporting Range Updates

In an effort to maintain our high diagnostic yield, while continuing to reduce variants of unknown significance (VUS) burden for clinicians and patients, we are also implementing minor changes to some gene-specific reporting ranges. The supporting rationale for these changes includes published literature related to mechanism of disease (POLD11, POLE1, KIT2,3, and PDGFRA4,5) and/ or data suggesting high VUS rates within certain gene regions and no internal evidence towards potential pathogenicity of these variants (PTEN6, MLH16, MSH26, and HOXB136-9).

Reporting Range Updates
Genes: POLD1, POLE Before Update: Reporting included missense variants within the exonuclease domain and other variant types regardless of their location within the gene. After Update: Reporting will include only missense and in-frame indel variants in the exonuclease domains. Gross del/dup analyses will no longer be available for these genes.
Gene: PTEN Before Update: Sequencing of the promoter region of PTEN (c.-1300 to c.-745) was performed and identified variants were reported. After Update: We will no longer routinely report promoter VUS in PTEN.
Genes: MLH1, MSH2 Before Update: Sequencing of the promoter region of MLH1 (c.-337 to c.-194), and MSH2 (c.-318 to c.-65) was performed and identified variants reported. After Update: We will no longer routinely report promoter VUS in MLH1 nor MSH2.
Gene: KIT Before Update: Reporting included all variant types throughout the gene. After Update: Only missense and in-frame indel variants in select coding exons (8, 9, 11, 13, and 17) will be routinely reported.
Gene: PDGFRA Before Update: Reporting included all variant types throughout the gene. After Update: Only missense and in-frame indel variants in select coding exons (9, 11, 13, and 17) will be routinely reported.
Gene: HOXB13 Before Update: Reporting included all variant types throughout the gene. After Update: Only variants impacting codon 84 are routinely reported.
