Invitae Bardet-Biedl Syndrome Panel
Use
The Invitae Bardet-Biedl Syndrome Panel analyzes genes associated with Bardet-Biedl Syndrome (BBS), a condition characterized by truncal obesity, cognitive impairment, rod-cone dystrophy, and renal abnormalities. Genetic testing for these genes can confirm a diagnosis and guide treatment and management decisions. Identification of a disease-causing variant informs recurrence-risk assessment and genetic counseling.
Special Instructions
The panel offers broad analysis of BBS-associated genes, selected based on current evidence. It allows efficient evaluation by covering various potential genes in a single clinical indication. Phenotype alone may not suffice for definitive diagnosis due to genetic heterogeneity.
Limitations
This assay provides >99% analytical sensitivity and specificity for single nucleotide variants, insertions, and deletions <15bp, and exon-level deletions/duplications. However, sensitivity may be slightly reduced for larger insertions/deletions between 15bp and a full exon. Some structural variants or variants in complex sequences may not be detected, and certain details may not be fully resolvable, such as mosaicism and gene conversions.
