Syndromic microphthalmia 6

Syndromic microphthalmia 6 is an autosomal dominant disorder caused by mutations of the BMP4 gene. In this sndrome, along with various facial dysmorphisms, various urogenital malfomations can be found.


Hereditary ocular disease and visual impairment
Aplasia of lacrimal and salivary glands
Fish-eye disease
Hereditary glaucoma
IVIC syndrome
Knobloch syndrome 1
Lacrimoauriculodentodigital syndrome
Ligneous conjunctivitis
Macular degeneration
Manitoba oculotrichoanal syndrome
Papillorenal syndrome
Retinitis pigmentosa
Syndromic microphthalmia 6
Usher syndrome
