Proboscis lateralis (PL) is a rare congenital facial abnormality characterized by failed development of the external nose on one side that is replaced by a tubular structure composed of skin and soft tissue usually attached at the inner canthus of the eye and therefore often associated with maldevelopment of the nasal cavity or paranasal sinuses of the affected side. PL is also associated with other craniofacial abnormalities such as orbital anomalies, cleft lip/palate, frontal encephalocele and holoprosencephaly (see these terms).

Infants usually develop ataxia, psychomotor delay and extraneurological manifestations including failure to thrive, enteropathy, hepatic dysfunction, coagulation abnormalities and cardiac and renal involvement. The phenotype is however highly variable and ranges from infants who die in the first year of life to mildly involved adults.

Autosomal recessive inheritance
Multifactorial inheritance
A special form of intestinal atresia with absence of mesentery, which is most likely due to an intrauterine intestinal vascular accident. Newborns are usually preterm infants with low birth-weights, that encounter feeding difficulties (including vomiting with initial feeds, which may later worsened and the abdomen becomes progressively distended) as well as failure to thrive. Affected children present disrupted bowel loops assuming a spiral configuration resembling an 'apple peel' and may have less than half of the normal length of the small bowel and a physiologically short bowel. This disorder is characterized by jejunal atresia near the ligament of Treitz, foreshortened bowel, and a large mesenteric gap. The bowel distal to the atresia is precariously supplied. It may be a manifestation of cystic fibrosis and the most important cause of mortality is short bowel syndrome, encountered in 65% of cases.

Craniosynostosis, Herrmann-Opitz type is a rare bone development disorder characterized by intellectual disability, short stature, turribrachycephaly, facial dysmorphism (i.e. severe hypertelorism, hypoplasia of supraorbital ridges, abnormal ears, and micrognathia), bony defects of the occiput, and digital anomalies (incl. syndactyly, oligodactyly, and/or brachydactyly). Urethral atresia has also been reported. There have been no further descriptions in the literature since 1987.

12q14 microdeletion syndrome is characterised by mild intellectual deficit, failure to thrive, short stature and osteopoikilosis. It has been described in four unrelated patients. The syndrome appears to be caused by a heterozygous deletion at chromosome region 12q14, which was detected in three of the four patients. The deleted region contains the LEMD3 gene: mutations in this gene have already been implicated in osteopoikilosis.

Autosomal dominant inheritance
Idiopathic multicentric osteolysis is a very rare syndrome characterized by progressive loss of bone, usually the capsal and tarsal bones, resulting in deformity and disability, as well as chronic renal failure in many cases. The bone and renal disorders are sometimes associated with intellectual deficit and facial abnormalities.

Micrognathia
Branchiootic syndrome is a rare, genetic multiple congenital anomalies syndrome characterized by second branchial arch anomalies (branchial cysts and fistulae), malformations of the outer, middle and inner ear associated with sensorineural, mixed or conductive hearing loss, and the absence of renal abnormalities. Typical ear findings consist of malformed auricles (e.g. lop or cupped ears), preauricular pits and/or tags, and middle and/or inner ear dysplasias (inculding cochlear, vestibular and semicircular channel hypoplasia, malformation of the ossicles and of middle ear space).

X-linked recessive inheritance
X-linked intellectual disability, Siderius type is characterised by mild to borderline intellectual deficit associated with cleft lip/palate. Preaxial polydactyly, large hands and cryptorchidism are sometimes present. The syndrome has been described in seven boys from two families. Transmission is X-linked and the syndrome is caused by mutations in the PHF8 gene, localised to the p11.21 region of the X chromosome.
