This lead to the diagnosis of NF1 microdeletion syndrome. 1 SHORT REPORT We present a first case report from Oman of a 20‐month‐old male child presenting with a neurofibromatosis‐1 phenotype combined with webbed neck and short stature. [onlinelibrary.wiley.com]

Case presentation Here we reported a patient carrying a novel de novo deletion at 17q11.2 adjacent to NF1 gene, who presented with developmental delay, short stature, postnatal microcephaly, underweight and dysmorphic features including flat facial profile [molecularcytogenetics.biomedcentral.com]

Here, we present another patient with 17q11.2 duplication and no signs of neurofibromatosis type 1, identified by array-CGH. We compared clinical features and genetic data with those of previously reported patients with 17q11.2 microduplications. [moh-it.pure.elsevier.com]

We present a 3 year old girl, born to consanguineous Sephardic Jewish parents, who are known carriers of Sandhoff disease, for which prenatal diagnosis was performed with normal results. [ashg.org]

Clinical Testing and Workup In the past, a specific chromosomal study known as G-band analysis, which demonstrates missing (deleted) material on chromosome 17p, was used to help obtain a diagnosis of SMS. [rarediseases.org]

It focuses on the genetics and molecular biology underlying these diseases, but also covers their clinical features, diagnosis and treatment, stressing the need for interdisciplinary medical care. [books.google.com]

The variable expressivity of the disease makes it challenging to establish genotype–phenotype correlations, which also affects prognosis and counselling. We here describe a 3-year-old NF1 patient with an atypical deletion and a complex phenotype. [moh-it.pure.elsevier.com]

Prognosis Because of the highly variable nature of SMS, it is impossible to generalize about prognosis for individual cases. [rarediseases.org]

Etiology Germline and mosaic microdeletions of the NF1 gene and its flanking regions caused by non-allelic homologous recombination are reported in patients with this disorder. Most occur de novo. [rareguru.com]
