Genomic rearrangements involving AUTS2 (7q11.22) are associated with autism and intellectual disability (ID), although evidence for causality is limited. By combining the results of diagnostic testing of 49,684 individuals, we identified 24 microdeletions that affect at least one exon of AUTS2, as well as one translocation and one inversion each with a… (More)
We report a series of eight patients with the Say/Barber/Biesecker/Young-Simpson (SBBYS) type of Ohdo syndrome, which is the largest cohort described to date. We expand on the type, frequency and severity of the clinical characteristics in this condition; comment on the natural history of Ohdo syndrome and further refine previously published diagnostic… (More)
The use of comparative genomic hybridization (CGH) and single nucleotide polymorphism (SNP) arrays has dramatically altered the approach to identification of genetic alterations that can explain intellectual disability and /or congenital anomalies. However, the discovery of numerous copy number changes with benign or unknown clinical significance has made… (More)
Interstitial microdeletions of 20q chromosome are rare, only 17 patients have been reported in the literature to date. Among them, only six carried a proximal 20q11.21-q11.23 deletion, with a size ranging from 2.6 to 6.8 Mb. The existence of a 20q11.2 microdeletion syndrome has been proposed, based on five previously reported cases that displayed anomalies… (More)
A second case of tetrasomy 20p due to an additional isochromosome 20p is reported. This resulted in a spontaneous intrauterine death with multiple congenital abnormalities. In keeping with the previous report, the foetus had poor ossification resulting in multiple long bone fractures.
We report a mother and son with an interstitial deletion of chromosome 2: del(2)(p21p22.2). Both have mildly dysmorphic facial features and learning difficulties. This phenotype contrasts with two previously described cases with a similar deletion that presented with cyclopia and alobar holoprosencephaly.
