NFIB Haploinsufficiency Is Associated with Intellectual Disability and Macrocephaly

2018

The nuclear factor I (NFI) family of transcription factors play an important role in normal development of multiple organs. Three NFI family members are highly expressed in the brain, and deletions or sequence variants in two of these, NFIA and NFIX, have been associated with intellectual disability (ID) and brain malformations. NFIB, however, has not previously been implicated in human disease. Here, we present a cohort of 18 individuals with mild ID and behavioral issues who are haploinsufficient for NFIB. Ten individuals harbored overlapping microdeletions of the chromosomal 9p23-p22.2 region, ranging in size from 225 kb to 4.3 Mb. Five additional subjects had point sequence variations c…

Pseudohypoparathyroïdie : Distorsion du ratio de transmission maternelle des mutations perte de fonction de GNAS

2020

National audience; La PseudoHypoParathyroïdie de type 1A (PHP1A) et la PseudoPseudoHypoparathyroïdie (PPHP) sont deux maladies rares à transmission autosomique dominante provoquées par des mutations perte de fonction du gène GNAS soumis à empreinte, codant la protéine Gsα. La PHP1A est causée par des mutations sur l’allèle maternel et entraîne une Ostéodystrophie Héréditaire d’Albright (AHO) et une résistance à la PTH, tandis que la PPHP avec AHO et sans résistance hormonale est liée à des mutations de l’allèle paternel. Cette étude visait à étudier la transmission des mutations de GNAS. Nous avons mené une étude rétrospective sur un grand nombre de familles mutées GNAS. Pour éviter un biai…
