Haplo insufficientie
Haploinsufficiency in genetics describes a model of dominant gene action in diploid organisms, in which a single copy of the wild-type allele at a locus in heterozygous combination with a variant allele is insufficient to produce the wild-type phenotype. Haploinsufficiency may arise from a de novo or … See more The alteration in the gene dosage, which is caused by the loss of a functional allele, is also called allelic insufficiency. An example of this is seen in the case of Williams syndrome, a neurodevelopmental disorder caused by … See more The most direct method to detect haploinsufficiency is the heterozygous deletion of one allele in a model organism. This can be done in See more • Ebert, BL; et al. (2008). "Identification of RPS14 as a 5q- syndrome gene by RNA interference screen". Nature. 451 (451): 335–340.
