Molecular analysis using FISH and polymorphic DNA markers detected an approximately 4 Mb, cytogenetically unidentified deletion occurring between two STSs markers, AFMB331YA9 and D8S1200, around the region of the distal inversion breakpoint. Although the deletion is large, mental retardation was not present in the patient. This is the first report of a cryptic deletion in a TRPS1 patient, both ends of which were analysed at the molecular level. The data obtained are useful for defining the location of the putative mental retardation gene(s) in TRPS1 and Langer-Giedion syndrome (TRPS2), as well as a locus for postaxial polydactyly.<\/jats:p>","DOI":"10.1136\/jmg.34.4.335","type":"journal-article","created":{"date-parts":[[2008,11,10]],"date-time":"2008-11-10T15:37:21Z","timestamp":1226331441000},"page":"335-339","source":"Crossref","is-referenced-by-count":7,"title":["A 4 Mb cryptic deletion associated with inv(8)(q13.1q24.11) in a patient with trichorhinophalangeal syndrome type I."],"prefix":"10.1136","volume":"34","author":[{"given":"T","family":"Sasaki","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H","family":"Tonoki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H","family":"Soejima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N","family":"Niikawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1997,4,1]]},"reference":[{"key":"ref_1","article-title":"Mendelian inheritance in man: catalogs of human genes and genetic disorders","author":"McKusick, V.A.","year":"1994","unstructured":"McKusick VA.
