Several rare variant phenotypes that have some overlap but deviate in some ways from the general pattern have also been described. The known variant phenotypes are spondyloepiphyseal dysplasia Maroteaux type (Pseudo\u2010Morquio type 2), parastremmatic dysplasia, and familial digital arthropathy with brachydactyly. Interestingly, different\n                    <jats:italic>TRPV4<\/jats:italic>\n                    mutations have been associated with dominantly inherited neurologic disorders such as congenital spinal muscular atrophy and hereditary motor and sensory neuropathy. Finally, a small number of patients have been identified in whom a\n                    <jats:italic>TRPV4<\/jats:italic>\n                    mutation results in a phenotype combining skeletal dysplasia with peripheral neuropathy. The\n                    <jats:italic>TRPV4<\/jats:italic>\n                    gene encodes a regulated calcium channel implicated in multiple and diverse cellular processes. Over 50 different\n                    <jats:italic>TRPV4<\/jats:italic>\n                    mutations have been reported, with two codons appearing to be mutational hot spots: P799 in exon 15, mostly associated with MD, and R594 in exon 11, associated with SMDK. While most pathogenic mutations tested so far result in activation of the calcium channel in vitro, the mechanisms through which TRPV4 activation results in skeletal dysplasia and\/or peripheral neuropathy remain unclear and the genotype\u2013phenotype correlations in this group of disorders remains somewhat mysterious. Since the phenotypic expression of most mutations seems to be relatively constant, careful clinical and radiographic assessment is useful in directing molecular analysis. \u00a9 2012 Wiley
