The defective gene, immunoglobulin mu-binding protein 2 ( IGHMBP2), is located on chromosome 11q13-q21. In this study, we screened the IGHMBP2 gene in 53 unrelated Han Chinese non-5q-spinal muscular atrophy patients and 100 healthy controls. Two novel mutations (c.711+1G&gt;C and c.1817G&gt;A) and 5 nucleotide polymorphisms (c.57T&gt;C, c.1554C&gt;T, c.1914G&gt;A, c.2080C&gt;T, and c.2270G&gt;C) were identified. However, only 1 patient harbored the compound heterozygous mutations (c.711+1G&gt;C, c.1817G&gt;A). Furthermore, the homozygous c.2636C&gt;A (p.T879\u00a0K) variation, which has been included as a mutation in the Human Gene Mutation Database, was found both in patients and healthy individuals. In conclusion, the IGHMBP2 gene was not found to be a major causative gene linked to Han Chinese non-5q-spinal muscular atrophy patients.<\/jats:p>","DOI":"10.1177\/0883073813497827","type":"journal-article","created":{"date-parts":[[2013,9,11]],"date-time":"2013-09-11T05:53:15Z","timestamp":1378878795000},"page":"NP35-NP39","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Variations
