Silver-Russell Syndrome and 12q14.3 microdeletion
0 Comment
Silver-Russell Syndrome (SRS) is a genetic disorder causing failure with prenatal and postnatal growth. Other common characteristics of SRS include a larger head at birth, protruding forehead in early life, body asymmetry and substantial feeding difficulties. SRS can be caused by different genetic mechanisms. The most common abnormalities are related... Read More

Population prevalence of copy number variants (CNVs)a first glimpse
Estimates of the population prevalence and inheritance patterns of recurrent copy number variants (CNVs) associated with neurodevelopmental disorders are lacking. This article presents a first glimpse. It is well known that chromosome microdeletions or microduplications in several areas (1q21.1, 3q29, 15q11, 15q13, 16p11.2, etc) are associated with a wide range... Read More

NF1 microdeletions and mutations gene location chromosome 17q11.2
Neurofibromatosis type 1 (NF1) is a hereditary syndrome. The main manifestations of this condition include café-au-lait spots, Lisch nodules and neurofibromas. It occurs in 1 to every 2000-3000 people. In most patients NF1 is caused by mutations of the NF1 gene, located at 17q11.2. However, 5-11% of patients have deletions... Read More

Delayed Neuropsychomotor Development and Seizures in a Patient with Ring Chromosome 20 – Candidate Genes
Delayed Neuropsychomotor Development and Seizures in a Patient with Ring Chromosome 20 – Candidate Genes Ring chromosomes are rare chromosomal abnormalities in which the long arm of the chromosome has been fused with the short arm. This often results in deletions and duplications of the chromosome. Ring Chromosome 20... Read More
