Preferred Label : Carpenter syndrome 1;
Symbol : CRPT1;
CISMeF acronym : CRPT1;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Acrocephalopolysyndactyly type II; Carpenter syndrome; Acps II;
Description : Carpenter syndrome is a rare autosomal recessive disorder with the cardinal features
of acrocephaly with variable synostosis of the sagittal, lambdoid, and coronal sutures;
peculiar facies; brachydactyly of the hands with syndactyly; preaxial polydactyly
and syndactyly of the feet; congenital heart defects; growth retardation; mental retardation;
hypogenitalism; and obesity. In addition, cerebral malformations, oral and dental
abnormalities, coxa valga, genu valgum, hydronephrosis, precocious puberty, and hearing
loss may be observed (summary by Altunhan et al., 2011). - Genetic Heterogeneity of
Carpenter Syndrome Carpenter syndrome-2 (CRPT2; 614976), in which the features of
Carpenter syndrome are sometimes associated with defective lateralization, is caused
by mutation in the MEGF8 gene (604267).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the Ras-associated protein RAB23 gene (RAB23, 606144.0001);
Prefixed ID : #201000;
Origin ID : 201000;
