PURPOSE: Within the Solve-RD project (https://solve-rd.eu/), the European
Reference Network for Intellectual disability, TeleHealth, Autism and Congenital
Anomalies aimed to investigate whether a reanalysis of exomes from unsolved
cases based on ClinVar annotations could establish additional diagnoses. We
present the results of the « ClinVar low-hanging fruit » reanalysis, reasons for
the failure of previous analyses, and lessons learned.
METHODS: Data from the first 3576 exomes (1522 probands and 2054 relatives)
collected from European Reference Network for Intellectual disability,
TeleHealth, Autism and Congenital Anomalies was reanalyzed by the Solve-RD
consortium by evaluating for the presence of single-nucleotide variant, and
small insertions and deletions already reported as (likely) pathogenic in
ClinVar. Variants were filtered according to frequency, genotype, and mode of
inheritance and reinterpreted.
RESULTS: We identified causal variants in 59 cases (3.9%), 50 of them also
raised by other approaches and 9 leading to new diagnoses, highlighting
interpretation challenges: variants in genes not known to be involved in human
disease at the time of the first analysis, misleading genotypes, or variants
undetected by local pipelines (variants in off-target regions, low quality
filters, low allelic balance, or high frequency).
CONCLUSION: The « ClinVar low-hanging fruit » analysis represents an effective,
fast, and easy approach to recover causal variants from exome sequencing data,
herewith contributing to the reduction of the diagnostic deadlock.
