If the mutation predates development of the breed it may exist in other collie breeds, as does Collie Eye Anomaly [ 13].
Duane-Radial Ray syndrome allelic to AROS is characterized by Duane eye anomaly, radial ray malformations like triphalangeal thumb, preaxial polydactyly, hypoplasia/aplasia of the thumb and radii, shortening and radial deviation of the forearm.
Your vet should do yearly eye checks on your dog for Progressive Retinal Atrophy (PRA) (causes total blindness), Retinal Dysplasia (causes eventual blindness), Collie Eye Anomaly (CEA) (usually inherited), cataracts (inherited), and entropion (when the dog's eyelids turn in or out).
Consequences of vertical infections includes microcephaly with brain and eye anomalies, and adult infections includes Guillain-Barrésyndrome (Gbrainbraischemiamyelitislitis and meningoencephalitis.
Several eye anomalies can be detected by a physical examination of this tissue, and therefore its "normal" characteristics need to be studied thoroughly.
Platform: Research Genetics (Invitrogen) - GF211 Microarray Filter Mendelian disorder: Marfan syndrome (MFS, OMIM #154700) Disease gene: fibrillin-1 precursor (FBN1, OMIM *134797) Phenotype: variable skeletal abnormalities, tall stature, disproportionately long limbs and digits, joint laxity, eye anomalies and progressive cardiovascular problems.
Several congenital muscular dystophies, referred to as dystroglycanopathies [8], [9] are associated with reduced ligand binding of DG and are characterized by defective neuronal migration (lissencephaly), severe mental retardation and eye anomalies [10], [11], [12], [13].
Platform: Agilent-012391 Whole Human Genome Oligo Microarray G4112A MFS Mendelian disorder: Marfan syndrome (MFS, OMIM #154700) Disease gene: fibrillin-1 precursor (FBN1, OMIM *134797) Phenotype: variable skeletal abnormalities, tall stature, disproportionately long limbs and digits, joint laxity, eye anomalies and progressive cardiovascular problems.
Other anomalies include other eye anomalies, anomalies of the neck, nose, trachea, skull shape and muscle.
The region R9 contains the TFAP2A gene, of which haploinsufficiency may be associated with eye anomalies [ 7, 20].
Affected individuals can also present with heart defects, cleft lip and/or palate, hearing impairment and eye anomalies.
