Phenotypic spectrum and incidence of TRPV4 mutations in patients with inherited axonal neuropathy.
Objective: To clarify the phenotypic spectrum and incidence of TRPV4 mutations in patients with inherited axonal neuropathies. Methods: We screened for TRPV4 mutations in 169 French unrelated patients with inherited axonal peripheral neuropathy. Ninety-five patients had dominant Charcot-Marie-Tooth type 2 (CMT2) disease, and 74 patients, including 39 patients with distal hereditary motor neuropathy, 14 with congenital spinal muscular atrophy and arthrogryposis, 13 with CMT2, and 8 with scapuloperoneal spinal muscular atrophy, presented with additional vocal cord paralysis and/or skeletal dysplasia. Results: No deleterious TRPV4 mutation was identified in the 95 patients with “pure” CMT2 (0/…
The 2q37-deletion syndrome: an update of the clinical spectrum including overweight, brachydactyly and behavioural features in 14 new patients
International audience; The 2q37 locus is one of the most commonly deleted subtelomeric regions. Such a deletion has been identified in >100 patients by telomeric fluorescence in situ hybridization (FISH) analysis and, less frequently, by array-based comparative genomic hybridization (array-CGH). A recognizable ‘2q37-deletion syndrome’ or Albright’s hereditary osteodystrophy-like syndrome has been previously described. To better map the deletion and further refine this deletional syndrome, we formed a collaboration with the Association of French Language Cytogeneticists to collect 14 new intellectually deficient patients with a distal or interstitial 2q37 deletion characterized by FISH and …
