Title: A new mutation of IGHMBP2 gene in spinal muscular atrophy with respiratory distress type 1. Author: Tachi N, Kikuchi S, Kozuka N, Nogami A. Journal: Pediatr Neurol; 2005 Apr; 32(4):288-90. PubMed ID: 15797190. Abstract: This report presents a new mutation in the first Japanese female infant with spinal muscular atrophy with respiratory distress type 1. She manifested the characteristic clinical features, including early-onset respiratory failure due to diaphragmatic paralysis and severe distal muscle weakness. Muscle biopsy in the femoral muscle indicated massive neurogenic changes. Sural nerve biopsy disclosed a moderate reduction of myelinated fibers, predominantly reduced large fibers. She had a novel homozygous missense mutation 2685 C -->A, leading to a T879K substitution in the immunoglobulin mu-binding protein 2 gene. Both parents were heterozygous for this mutation.[Abstract] [Full Text] [Related] [New Search]
