Partial Tetrasomy 6p comparable to Trisomy Distal 6p Phenotype
0 Comment
Tetrasomy 6p caused by a small supernumerary marker chromosome presenting Trisomy distal 6p Phenotype. A small supernumerary marker chromosome (sSMC) is a structurally abnormal additional chromosome that most often lacks a distinct banding pattern and is difficult to identify by conventional banding cytogenetic analysis. Approximately 70% of such chromosomes occur... Read More

Partial trisomy 6p
Partial trisomy 6p is a rare chromosomal anomaly associated with low birth weight, developmental delay, craniofacial abnormalities, feeding difficulties, congenital heart defects and renal abnormalities. In most previously reported cases trisomy 6p was associated with the partial monosomy of another chromosome, often due to parental balanced translocation. This further... Read More

WAGR syndrome 11p13 deletion
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
