Genetic and clinical screening for hereditary primary hyperparathyroidism in a large Chinese cohort: a single‐center study

J Bone Miner ResPublished Cross-sectional study

Study context

Population
Newly diagnosed Han primary hyperparathyroidism (PHPT) patients consenting to genetic screening, large academic center in Beijing, China
Participants
394 participants
Exposure
Hereditary vs nonhereditary PHPT
  • Hereditaryn = 74
  • Nonhereditaryn = 262reference
Outcome
Proportion and composition of hereditary PHPT
Methodological detailssingle-centre, genetic screening (targeted NGS with MEN1-MLPA and CDC73-MLPA)
  • Single-centre
  • Genetic screening (targeted NGS with MEN1-MLPA and CDC73-MLPA)

Main finding

As reported in the abstract

Hereditary PHPT (genetic and clinical screening)
Rate of hereditary PHPT
18.8% (74/394)
Rate of unequivocal nonhereditary PHPT
66.5% (262/394)
Unclassifiable: no clinical features of hereditary PHPT but variants of uncertain significance
14.7% (58/394)
P/likely pathogenic (LP) variant detection rate (targeted next-generation sequencing (T-NGS) 41 patients + MLPA long-range deletions 3 patients)
11.2% (44/394)
Clinically diagnosed MEN1
30 patients

Observational data: associations, not effects.
