Primary microcephaly (MCPH) is a clinical diagnosis made when an individual has a head circumference more than 3 standard deviations below the age- and sex-matched population mean and mental retardation, with no other associated malformations and with no apparent etiology. Most cases of primary microcephaly show an autosomal recessive mode of inheritance (summary by Woods et al., 2005).For a general phenotypic description and a discussion of genetic heterogeneity of primary microcephaly, see MCPH1 (OMIM ).

BTDD is an autosomal dominant disorder characterized by brachycephaly, trichomegaly, and developmental delay. Although it is caused by dysfunction of the ribosome, patients do not have anemia (summary by Paolini et al., 2017).

Autosomal recessive brachyolmia-amelogenesis imperfecta syndrome is an exceedingly rare form of brachyolmia (see this term), characterized by mild platyspondyly, broad ilia, elongated femoral necks with coxa valga, scoliosis, and short trunked short stature associated with amelogenesis imperfecta (see this term) of both primary and permanent dentition.

Among the Yakuts, an Asian population isolate that is located in the northeastern part of Siberia, Maksimova et al. (2010) ascertained a short stature syndrome involving autosomal recessive postnatal growth failure, small hands and feet, loss of visual acuity with abnormalities of color vision, abnormal nuclear shape in neutrophil granulocytes (Pelger-Huet anomaly; see {169400}), and normal intelligence.

Progeroid syndrome, Petty type is a rare premature aging syndrome characterized by pre-and postnatal growth retardation, a congenital premature-aged appearance with distinctive craniofacial dysmorphism (wide calvaria with large open anterior fontanel and wide metopic suture, broad forehead, small face, micrognathia), markedly diminished subcutaneous fat, cutis laxa and wrinkled skin, without delay in psychomotor development. Scant, brittle hair, hypoplastic nails and delayed, abnormal dentition, as well as hypoplastic distal phalanges, umbilical hernia and eye abnormalities (myopia/hyperopia, strabismus), are also commonly associated.
