Additional common features include small corpus callosum, normal birth length and head circumference, postnatal growth restriction, low anterior hairline, upturned nose, bilateral preauricular pits, widely spaced teeth, gingival hypertrophy, left ventricular dilatation with decreased biventricular systolic function, delayed bone age, 5th finger clinodactyly, short 3rd digit, hyperconvex nails, obstructive and central sleep apnea, and bilateral heel contractures. Fluorescence in situ hybridization (FISH) performed in the mother of both children showed an apparently balanced, intrachromosomal insertional translocation of 1q21.3q23.3 to 1q42.12. The sibling recurrence likely arose by a maternal meiotic crossing over on the rearranged chromosome 1 between the deleted region and the insertion. We hypothesize that the decreased cardiac function and contractures may be related to <jats:italic>LMNA<\/jats:italic> haploinsufficiency. This case illustrates the importance of FISH when attempting to determine inheritance of a copy\u2010number variation and emphasize the value of evaluating known haploinsufficiency phenotypes for genes in deleted regions. \u00a9 2012 Wiley Periodicals, Inc.<\/jats:p>","DOI":"10.1002\/ajmg.a.35563","type":"journal-article","created":{"date-parts":[[2012,8,17]],"date-time":"2012-08-17T21:31:47Z","timestamp":1345239107000},"page":"2591-2601","source":"Crossref","is-referenced-by-count":7,"title":["Maternal intrachromosomal insertional translocation leads to recurrent 1q21.3q23.3 deletion in two siblings"],"prefix":"10.1002","volume":"158A","author":[{"given":"Shane C.","family":"Quinonez","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Hedera","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mason","family":"Barr","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Todd","family":"Ackley","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cindy","family":"Lam","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anjali","family":"Purkayastha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas W.","family":"Glover","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey W.","family":"Innis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,8,17]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/GIM.0b013e318177015c"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-0004.1985.tb00242.x"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000261254.87181.80"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/humu.20807"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/6799"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/1531-8249(200008)48:2<170::AID-ANA6>3.0.CO;2-J"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajhg.2011.10.008"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/humu.21233"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.17.6.483"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00200903"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.33278"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.2008.058701"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.1320450604"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1597\/1545-1569(1993)030<0586:PDOTLA>2.3.CO;2"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00296461"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.35.12.1047"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00278708"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.32006"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1038\/ejhg.2011.157"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.23.3.242"},{"key":"e_1_2_6_22_1","unstructured":"Online Mendelian Inheritance in Man OMIM (TM).
