STRA6-associated syndrome

Tuesday 27 March 2007

Synopsis

- anophthalmia
- distinct eyebrows
- cardiac malformations
- diaphragmatic hernia
- alveolar capillary dysplasia
- lung hypoplasia
- mental retardation

Etiology

- germline mutations in STRA6 (17273977)

  • STRA6 encodes an integral cell-membrane protein that favors RA uptake from soluble retinol-binding protein; its transcription is directly regulated by RA levels. (17503335)
  • STRA6 is a member of a large group of "stimulated by retinoic acid" genes encoding novel transmembrane proteins, transcription factors, and secreted signaling molecules or proteins of largely unknown function. (17273977)
