Also, a rare recombination between DXS548 and FRAXAC1 was recorded in the maternal meiosis. Follow up of the neonate confirmed the same DNA genotype as in the CVS, but the child died of DiGeorge syndrome after four days and was subsequently found to carry a microdeletion of chromosome 22 using probe cEO. It is suggested that in this family the deletion of chromosome 22 is likely to be a chance event but the rare recombinant and the fragile X mutation might be causally related.<\/jats:p>","DOI":"10.1136\/jmg.32.3.236","type":"journal-article","created":{"date-parts":[[2008,11,10]],"date-time":"2008-11-10T15:23:16Z","timestamp":1226330596000},"page":"236-239","source":"Crossref","is-referenced-by-count":16,"title":["Unusual (CGG)n expansion and recombination in a family with fragile X and DiGeorge syndrome."],"prefix":"10.1136","volume":"32","author":[{"given":"J N","family":"Macpherson","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G","family":"Curtis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J A","family":"Crolla","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N","family":"Dennis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B","family":"Migeon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P K","family":"Grewal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M C","family":"Hirst","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K E","family":"Davies","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P A","family":"Jacobs","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[1995,3,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1711","DOI":"10.1126\/science.1675488","article-title":"Mapping of DNA instability at the fragile X to a trinucleotide repeat sequence p(CCG)n","volume":"252","author":"Kremer, E.J.; Pritchard, M.; Lynch, M.","year":"1991","unstructured":"Kremer EJ, Pritchard M, Lynch M, et al.
