14q32 deletions and elevated cancer risk
0 Comment
Deletions within chromosome 14q32 – a region within the long arm of chromosome 14 – are rare. Because of this, research on this deletion is scarce. Symptoms of 14q32 deletions include intellectual disability, developmental delay, dysmorphic features, microcephaly (an abnormally small and underdeveloped head), and hypotonia (low muscle tone). Severity... Read More

7p15 deletion as the cause of hand-foot-genital syndrome
7p15 deletion as the cause of hand-foot-genital syndrome. Hand-foot-genital syndrome (HFGS) is a rare genetic disorder that is characterized by malformations in the hands, feet and the genitourinary tract. The most frequent limb abnormalities in HFGS include short thumbs and fingers, small feet, clinodactyly (curvature) of the fifth finger, and... Read More

BPTF gene mutation 17q24.2 deletion – microcephaly, developmental and speech delay
Chromatin remodeling is essential for DNA accessibility and gene regulation, and its disruption leads to a variety of disorders. The protein complex NURF (nucleosome remodeling factor) involved in chromatin remodeling is important in regulating fetal development. NURF contains the proteins SNF2L, pRBAP46/48, and BPTF. BPTF, in particular, is expressed throughout... Read More
