| Syndrome | Symptoms | Inheritance |
| Bickers-Adams (x-linked hydrocephalus HSAS) | aqueductal stenosis adduction deformities of the thumbs L1CAM gene mutation | x chromosmal recessive |
| Hydrocephalus without aqueductal stenosis | mental retardation | x chromosomal recessive |
| Hydrolethalus | microphthalmia polydactyly congenital heart disease pulmonal hypoplasia | autosomal recessive |
| Meckel | polycystic kidneys polydactyly encephalocele | autosomal recessive MKS1: chr 17 MKS2: chr 11 MKS3: chr 8 |
| VACTERL association | vertebral anomalies of the spine anal atresia congenital heart disease tracheo-esophageal fistula renal abnormalities limb malformations | when associated with hydrocephalus: autosomal recessive or x-linked |
| VATER association | macrocephaly ventriculomegaly | autosomal recessive |
| Waaler-Aarskog | Sprengel anomaly (undescended scapula) costovertebral dysplasia | probably autosomal dominant |
