The study of Trisomy 8p has been mentioned in research publications which can be found using our bioinformatics tool below. A female patient with mosaicism for partial monosomy 8p and partial trisomy 8p is presented. Her karyotype is 46,XX, del(8)(p21)/46,XX, dup(8)(p21----pter). She showed minimal dysmorphic features, agenesis of the corpus callosum and moderate developmental delay. The manifestations of these two patients resemble those of mosaic trisomy 8 and mosaic trisomy 8p, with rib and vertebral abnormalities, absent corpus callosum, and enlarged cerebral ventricles.

Complete trisomy 8 causes severe effects on the developing fetus and can be a cause of miscarriage. Complete trisomy 8 is usually an early lethal condition, whereas trisomy 8 mosaicism is less severe and individuals with a low proportion of affected cells may exhibit a comparatively mild range of physical abnormalities and developmental delay.

Main features Some people with fairly small amounts of extra 8p material in particular segments are healthy, develop normally and have healthy children. This is especially true in families where different members have the same duplication and are all healthy.

Another chromosomal condition called inversion duplication 8p is caused by a rearrangement of genetic material on the short (p) arm of chromosome 8. This rearrangement results in an abnormal duplication and an inversion of a segment of the chromosome. Individuals diagnosed with chromosome 8p inverted duplication deletion (invdupdel(8p)) manifest a wide range of clinical features and cognitive impairment. The purpose of this study is to employ array CGH technology to define more precisely the cytogenetic breakpoints and regions of copy number vari … Vid trisomy rescue kan de två kvarvarande kromosomerna ha nedärvts från samma förälder, det vill säga antingen från mamman eller från pappan (uniparental disomi, UPD). Detta saknar oftast betydelse, förutom när kromosomen innehåller gener som endast uttrycks vid nedärvning från en specifik förälder (präglade gener). This video is focused on people affected by abnormalities on chromosome 8, 8p, 8q, or both.
