Conditions with this feature

Weaver syndrome
MedGen UID:
Concept ID:
Disease or Syndrome
EZH2-related overgrowth includes EZH2-related Weaver syndrome at one end of the spectrum and tall stature at the other. Although most individuals diagnosed with a heterozygous EZH2 pathogenic variant have been identified because of a clinical suspicion of Weaver syndrome, a minority have been identified through molecular genetic testing of family members of probands or individuals with overgrowth who did not have a clinical diagnosis of Weaver syndrome. Thus, the extent of the phenotypic spectrum associated with a heterozygous EZH2 pathogenic variant is not yet known. Weaver syndrome is characterized by tall stature, variable intellect (ranging from normal intellect to severe intellectual disability), characteristic facial appearance, and a range of associated clinical features including advanced bone age, poor coordination, soft doughy skin, camptodactyly of the fingers and/or toes, umbilical hernia, abnormal tone, and hoarse low cry in infancy. Brain MRI has identified abnormalities in a few individuals with EZH2-related overgrowth. Neuroblastoma occurs at a slightly increased frequency in individuals with a heterozygous EZH2 pathogenic variant but data are insufficient to determine absolute risk. There is currently no evidence that additional malignancies (including hematologic malignancies) occur with increased frequency.
Terminal osseous dysplasia-pigmentary defects syndrome
MedGen UID:
Concept ID:
Disease or Syndrome
Terminal osseous dysplasia is an X-linked dominant male-lethal disease characterized by skeletal dysplasia of the limbs, pigmentary defects of the skin, and recurrent digital fibroma during infancy (Sun et al., 2010).
Desbuquois dysplasia 2
MedGen UID:
Concept ID:
Disease or Syndrome
Desbuquois dysplasia, which belongs to the multiple dislocation group of disorders, is characterized by dislocations of large joints, severe pre- and postnatal growth retardation, joint laxity, and flat face with prominent eyes. Radiologic features include short long bones with an exaggerated trochanter that gives a 'monkey wrench' appearance to the proximal femur, and advanced carpal and tarsal ossification (summary by Bui et al., 2014). For a discussion of genetic heterogeneity of Desbuquois dysplasia, see DBQD1 (251450).
Intellectual developmental disorder, autosomal dominant 66
MedGen UID:
Concept ID:
Mental or Behavioral Dysfunction
Autosomal dominant intellectual developmental disorder-66 (MRD66) is characterized by global developmental delay with mildly to moderately impaired intellectual development and mild speech delay. The phenotype and severity are highly variable. Some patients have behavioral problems or autism spectrum disorder, and about 50% have variable types of seizures. Additional features may include nonspecific dysmorphic facial features, tall or short stature, and mild skeletal anomalies (Rahimi et al., 2022).
Intellectual developmental disorder, autosomal dominant 71, with behavioral abnormalities
MedGen UID:
Concept ID:
Mental or Behavioral Dysfunction
Autosomal dominant intellectual developmental disorder-71 with behavioral abnormalities (MRD71) is a neurodevelopmental disorder characterized by global developmental delay with hypotonia, speech delay, and variably impaired cognitive development. Almost all affected individuals show marked behavioral manifestations, including autism spectrum disorder (ASD), ADHD, hypersensitivity, and aggression. Many have dysmorphic features, although there is not a common gestalt (Harris et al., 2021).
