| alagille syndrome | <syndrome> Hypoplasia of the hepatic ducts, congenital pulmonary artery stenosis, facial abnormalities, and other congenital malformations, particularly skeletal. It is often presented as jaundice during the neonatal period. It is an autosomal recessive disease generally manifesting during childhood.

Since it is usually autosomal dominant one or both parents also have the disorder. Surgery is used to correct skull and facial abnormalities. Inheritance: autosomal dominant. (27 Sep 1997) |
| Alport's syndrome | <syndrome> Progressive microscopic haematuria leading to chronic renal failure earlier in males, accompanied by defects such as sensorineural hearing loss, lenticonus, and maculopathy; autosomal dominant, autosomal recessive, and X-linked forms known. (05 Mar 2000) |
| Alport syndrome | <syndrome> An uncommon inherited disorder involving damage to the kidneys, haematuria and hearing loss. In some individuals vision may also be affected. Symptoms include loss of hearing, abnormal colour to urine, swelling, cough and decline in vision. Incidence: 1 in 50,000. Inheritance: sex-linked autosomal dominant. (15 Nov 1997) |
| Alstrom's syndrome | <syndrome> Retinal degeneration with nystagmus and loss of central vision, associated with obesity in childhood; sensorineural hearing loss and diabetes mellitus usually occur after age 10; autosomal recessive inheritance. (05 Mar 2000) |
| amenorrhoea-galactorrhoea syndrome | <syndrome> Unphysiologic lactation from endocrinological causes or from a pituitary tumour. (05 Mar 2000) |

They may be associated with intrauterine amputations. (12 Dec 1998) |
