Alternative titles and symbols : Ear, patella, short stature syndrome; EPS; Microtia, absent patellae, micrognathia syndrome; Meier-gorlin syndrome;
Description : The Meier-Gorlin syndrome is a rare autosomal recessive disorder characterized by
severe intrauterine and postnatal growth retardation, microcephaly, bilateral microtia,
and aplasia or hypoplasia of the patellae (summary by Shalev and Hall, 2003). While
almost all cases have primordial dwarfism with substantial prenatal and postnatal
growth retardation, not all cases have microcephaly, and microtia and absent/hypoplastic
patella are absent in some. Despite the presence of microcephaly, intellect is usually
normal (Bicknell et al., 2011). - Genetic Heterogeneity of Meier-Gorlin Syndrome Also
see Meier-Gorlin syndrome-2 (613800), caused by mutation in the ORC4 gene (603056)
on chromosome 2q22; Meier-Gorlin syndrome-3 (613803), caused by mutation in the ORC6
gene (607213) on chromosome 16q12; Meier-Gorlin syndrome-4 (613804), caused by mutation
in the CDT1 gene (605525) on chromosome 16q; and Meier-Gorlin syndrome-5 (613805),
caused by mutation in the CDC6 gene (602627) on chromosome 17q21.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the origin recognition complex, subunit 1, gene (ORC1, 601902.0001);
