Further phenotypic expansion of 15q11.2 BP1–BP2 microdeletion (Burnside-Butler) syndrome
Open accessAbstract
We report a 10-year-old Caucasian male identified with copy number variation detected by microarray analysis including a maternally inherited 15q11.2 microdeletion involving 4 genes, paternally inherited 13q12.2 microdeletion with 10 genes, and a de novo 2q14.3 duplication involving 4 genes. He had a history of speech delay, cognitive deficits, attention deficit hyperactivity disorder and a posterior lenticonus cataract removed at 5 yr of age. The genes on chromosomes 2 and 13 are not known to be involved with cataract formation, which lends further support of the role of the 15q11.2 region and additional evidence for phenotypic expansion of the 15q11.2 BP1-BP2 microdeletion (termed Burnside-Butler) syndrome.

Individuals have been reported with the 15q11.2 BP1-BP2 microdeletion and additional non-neurological clinical findings including congenital cataracts, proximal esophageal atresia and distal tracheoesophageal fistula (type C), and congenital arthrogryposis.
“Recently, individuals have been reported with the 15q11.2 BP1–BP2 microdeletion and additional non-neurological clinical findings. These findings included congenital cataracts [14,35], proximal esophageal atresia and distal tracheoesophageal fistula (type C) [35] and congenital arthrogryposis [36].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
