  • Parental variant study (PVS) was informative for 45% of genes with VUS
  • PVS was most likely to be informative for genes associated with a well described syndrome, e.g., CHARGE, Kleefstra, Rubinstein-Taybi syndrome, or severe early-onset phenotype, e.g., infantile epileptic encephalopathy
  • PVS was least likely to be informative in genes with multiple inheritance patterns, incomplete penetrance, variable expressivity, or non-specific disease phenotype
