Hypothesis

NLRP2 has a previously unrecognised role in establishing or maintaining genomic imprinting in humans.

Conclusion

The study identifies a homozygous frameshift mutation in NLRP2 in a family with Beckwith-Wiedemann syndrome, suggesting its role in genomic imprinting.

Supporting Evidence

  • The study reports a family with BWS and an IC2 epimutation.
  • Genetic analysis revealed a homozygous frameshift mutation in NLRP2 in the mother.
  • Previous studies linked NLRP7 mutations to familial hydatidiform mole, but this is the first report of NLRP2 mutation in human disease.

Takeaway

This study found a gene mutation in a family that causes a growth disorder in children, showing that this gene helps control how genes are turned on and off.

Methodology

The study involved genetic analysis of a consanguineous family and additional BWS families to identify mutations in NLRP2.

Limitations

The study primarily focused on a small number of families, which may limit the generalizability of the findings.

Participant Demographics

The family studied was of Pakistani origin, with two affected children and their parents.
