LAB1755 Germline Familial Variant Testing (DH MyExome)
LAB1846 Germline Familial Variant Testing (DH MyExome) —LAB ONLY
Test Information
Ordering Germline NGS panels and Exome sequencing is only available by referral or prior consult with Genetics providers at DH-H. To request a buccal kit, contact LABCRC@hitchcock.org
Currently this isbeing offered for targeted variant testing for parents or siblings for pathogenic, likely pathogenic variants, and variants of uncertain significance.
Please note that familial variant testing will generally not be recommended with respect to following scenarios
Variant is in a preliminary evidence gene, gene-disease relationship is weak, limited evidence
A variant is detected in a single gene(e.g. VOUS) with an AR phenotype and no second hit can be detected or resolved for phase
The minor allele frequency of the variant is high with respect to the incidence of the disease/phenotype
