Using the N-ethyl-N-nitrosourea (ENU) mutagenesis screen, we have identified two skeletal morphology mutants, Skm1 and Skm2. Positional cloning and candidate gene sequencing localized the causative point mutations within the genes coding for natriuretic peptide receptor C (NPR-C) and filamin b (FLNB), respectively. Mice that carry a mutation in Npr3 exhibit a skeletal overgrowth phenotype, resulting in an elongated body and kyphosis. Skm2 mice, carrying a mutation in Flnb, present with scoliosis and lordosis. These mutant mice will serve as useful models for the study of vertebral malformations.

Spondylocarpotarsal synostosis syndrome, a rare syndromic skeletal disorder characterized by disrupted vertebral segmentation with vertebral fusion, scoliosis, short stature, and carpal/tarsal synostosis, has been associated with biallelic truncating mutations in the filamin B gene or monoallelic mutations in the myosin heavy chain 3 gene. We herein report the case of a patient with a typical phenotype of spondylocarpotarsal synostosis syndrome who had a homozygous frameshift mutation in the refilin A gene (RFLNA) [c.241delC, p.(Leu81Cysfs*111)], which encodes one of the filamin-binding proteins. Refilins, filamins, and myosins play critical roles in forming perinuclear actin caps, which change the nuclear morphology during cell migration and differentiation. The present study implies that RFLNA is an additional causative gene for spondylocarpotarsal synostosis syndrome in humans and a defect in forming actin bundles and perinuclear actin caps may be a critical mechanism for the development of spondylocarpotarsal synostosis syndrome.
