In Brief: The study established a novel rat model with a clinically relevant PLS3 mutation, which replicates the osteoporotic phenotype of early-onset PLS3-related osteoporosis. The findings suggest that treatment with alendronate or teriparatide improves bone mass and microarchitecture, suggesting their potential as effective treatments for early-onset osteoporosis caused by PLS3 mutations.Commentary: This study is an essentia...

3.13. Loss-of-function variant in SPIN4 causes an X-linked overgrowth syndrome

JC Lui , J Wagner , E Zhou , L Dong , KM Barnes , YH Jee , J Baron

In Brief: These authors identify a frameshift truncating variant in the gene SPIN4 (Spindlin member 4) in a patient with skeletal overgrowth, hepatosplenomegaly and macrocephaly. Using state-of-the-art mouse models and histone peptide arrays, they delineate the underlying pathogenic mechanism and show that SPIN4 positively regulates Wnt signalling by functioning as an epigenetic reader.Commentary: Generalized overgrowth disorders are ch...
