brachydactyly/proline

BACKGROUND Brachydactyly type A2 (OMIM 112600) is characterised by hypoplasia/aplasia of the second middle phalanx of the index finger and sometimes the little finger. BDA2 was first described by Mohr and Wriedt in a large Danish/Norwegian kindred and mutations in BMPR1B were recently demonstrated

Autosomal recessive Robinow syndrome (RRS) is a severe skeletal dysplasia with short stature, generalized limb shortening, segmental defects of the spine, brachydactyly, and a dysmorphic facial appearance. The gene encoding receptor orphan receptor tyrosine kinase 2 (ROR2) is located on chromosome

We describe a patient with autism and brachymetaphalangy, meeting criteria for 2q37 deletion syndrome (also called Albright Hereditary Osteodystrophy-like syndrome or Brachydactyly-Mental Retardation syndrome, OMIM 600430). Our molecular cytogenetic studies, including array comparative genomic

Mutations in the receptor tyrosine kinase Ror2 account for Brachydactyly type B and Robinow Syndrome. We have identified two novel factors interacting with the Ror2 intracellular domain. TAK1 (TGF-beta activated kinase 1), a MAP3K, interacts with Ror2 and phosphorylates its intracellular

The mammalian Ror family receptor tyrosine kinases, Ror1 and Ror2, play crucial roles in developmental morphogenesis. Although the functions of Ror1 and Ror2 are redundant, Ror2 exhibits more specific functions during development. We show that when expressed in mammalian cells, Ror2, but not Ror1,

Pseudohypoparathyroidism (PHP) refers to end-organ resistance that primarily impairs the renal actions of parathyroid hormone (PTH). The patients with PHP type Ia (PHP-Ia), one of the 4 types of PHP, show resistance to other peptide hormones as well as clinical features of Albright hereditary

OBJECTIVE A recurrent point mutation in the fibroblast growth factor receptor 3 gene that converts proline 250 into arginine has been reported recently in cases of apparently nonsyndromic coronal craniosynostosis. The goal of the present study was to examine the phenotype of patients in whom this
