Limb deficiencies distal with micrognathia

The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.

The distal limb deficiencies-micrognathia syndrome is characterized by the combination of symmetric severe distal limb reduction deficiencies affecting all four limbs (oligodactyly), microretrognathia, and microstomia with or without cleft palate.

It has been reported in four patients; two of them were siblings and had moderate intellectual deficiency.

Two non-related subjects also had severe myopia, bilateral conductive hearing loss and a renal change, referred to as oligomeganephronia, or renal hypoplasia.

Using high resolution oligoarray-based comparative genomic hybridization (aCGH), a 10q24 duplication or triplication was recently detected in all these patients, similar to the duplication detected in an isolated form of split hand foot malformation (SHFM; see this term).
