Clinical characterization of individuals with the distal 1q21.1 microdeletion
Clinical characterization of individuals with the distal 1q21.1 microdeletion is described in this summary. Deletions of the 1q21.1 segment may be subdivided into two groups: proximal (located in the interval of 144.9-146.2 Mb) and distal (~146.4-148.8 Mb). Proximal del 1q21.1 in the presence of modifying variant in RBM8A leads to... Read More

Chromosome 7q11.23 deletion and duplication
Chromosome 7q11.23 deletions and duplications cause different symptoms. Segment 7q11.23 contains 25-27 genes. Both deletions and duplications of this segment are known to cause different disorders. Deletions of 7q11.23 cause (a well-recognized) Williams syndrome; duplication of 7q11.23 cause a wide range of clinical manifestations that are hard to recognize... Read More
