WAGR syndrome 11p13 deletion
0 Comment
WAGR syndrome is a rare genetic disorder associated with the deletion of chromosome 11p13, involving genes WT1 and PAX6, and features Wilms’ tumor, aniridia, genitourinary anomalies, as well as varying degrees of intellectual disabilities. Some other findings may include obesity, glaucoma, cataracts, kidney failure, congenital diaphragmatic hernia, and autism. Wang... Read More

Interstitial deletions in proximal regions of 6q
Interstitial microdeletions in the proximal region of the long arm (q) of chromosome 6 are rare. There have been previous studies that show a correlation between a candidate gene SIM1 located at 6q16.3 and Prader-Willi syndrome (PWS)-like clinical manifestations such as hypotonia and developmental delay. Machida et al. present 12... Read More

GBC3 deletion mutation and Precocious puberty in a case of Simpson–Golabi–Behmel syndrome
GPC3 mutation/deletion and Simpson-Golbai-Behmel syndrome (SGBS). This syndrome is characterized by pre- and post- macrosomia and distinctive craniofacial features such as macrocephaly, coarse facial features, and palatal abnormalities. Mild-to-severe intellectual disability with or without structural brain anomalies are also commonly noted. Other variable findings include supernumerary nipples, diastasis recti,... Read More

12q21 Interstitial Deletions Review of the Literature
The segment 12q21 is relatively large (21.2 Mb) but contains only 60 genes. Such low gene density allows the evaluation of the potential role of each gene. Recently a 1.6 Mb critical region (CR) has been determined for rare 12q21 deletions’ most commonly described clinical features. Recalcati et al. reported... Read More

Phenotypic Variability in Phelan–McDermid Syndrome and Its Putative Link to Environmental Factors
Phelan-McDermid Syndrome phenotypic variability and its link to environmental factors. Phelan-McDermid Syndrome (PMS) is categorized by different genetic abnormalities in the SHANK3 gene, chromosomal rearrangements and/or deletion at 22q13. The size of deletion may vary from 100 Kb to over 9 Mb and large deletions may involve many additional genes.... Read More
