Bosch-Boonstra-Schaafov sindrom optičke atrofije jest rijetko autosomno nasljedno stanje koje karakterizira zaostajanje u razvoju, intelektualna invalidnost i smanjena oštrina vida.^[2]^[3]^[4]

Ispoljavanje uredi

Svi opisani pacijenti patili su od zaostajanja u razvoju, intelektualne ometenosti (raspon koeficijenta inteligencije 48–74) i smanjene vidne oštrine. Očne abnormalnosti uključuju male diskove, blijede diskove, ekskavaciju diska, strabizam i latentni nistagmus.

Ostale karakteristike ovog stanja su donekle varijabilne i uključuju

Nega lica
- Naborane uši
- Spiralne anomalije
- Mali nosni greben
- Visoki nosni most
- Zaokrenut nos
- Epikanusne nabore
- Uzdignute palpebralne pukotine
Skeletni
- Konusni prsti
- Hipotonija

Genetika uredi

Ovo stanje je uzrokovano mutacijama u genu NR2F1, na dugom kraku hromosoma 5 (5q15). Gen kodira protein koji djeluje kao jedarni receptor i regulator transkripcije. Ovo stanje se nasljeđuje po obrascu autosomno dominantnih svojstava.

Epidemiologija uredi

Ovo stanje se smatra rijetkim, s manje od 50 slučajeva opisanih u literaturi do 2019.

Historija uredi

Ovo stanje je prvi put opisano 2014.^[5]
