Partial trisomy 6p
0 Comment
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 contributes to the difficulty of... 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 patients (6 females and 6... 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, congenital heart defects, diaphragmatic hernia,... Read More
