| Cleft lip/palate-deafness-sacral lipoma syndrome is characterized by cleft lip/palate, profound sensorineural deafness, and a sacral lipoma. It has been described in two brothers of Chinese origin born to non-consanguineous parents. Additional findings included appendages on the heel and thigh, or anterior sacral meningocele and dislocated hip. The mode of inheritance is probably autosomal or X-linked recessive. |

| Lethal left ventricular non-compaction-seizures-hypotonia-cataract-developmental delay syndrome is rare, genetic, neurometabolic disease characterized by global developmental delay, severe hypotonia, seizures, cataracts, cardiomyopathy (including left or bi-ventricular hypertrophy, dilated cardiomyopathy) and left ventricular non-compaction, typically resulting in infantile or early-childhood death. Patients usually present metabolic lactic acidosis, failure to thrive, head lag, respiratory problems and decrease in respiratory chain complex activity. Highly variable cerebral abnormalities have been reported and include microcephaly, prominent extra-axial cerebrospinal fluid spaces, diffuse neuronal loss and cortical/white matter gliosis. |
