Summaries for Macrocephaly, Dysmorphic Facies, and Psychomotor Retardation

OMIM : 57 Macrocephaly, dysmorphic facies, and psychomotor retardation (MDFPMR) is an autosomal recessive neurodevelopmental disorder characterized by large head and somatic overgrowth apparent at birth followed by global developmental delay. Affected individuals have characteristic dysmorphic facial features and persistently large head, but increased birth weight normalizes with age. Additional neurologic features, including seizures, hypotonia, and gait ataxia, may also occur. Patients show severe intellectual impairment (summary by Ortega-Recalde et al., 2015). (617011)

MalaCards based summary : Macrocephaly, Dysmorphic Facies, and Psychomotor Retardation, is also known as mdfpmr. An important gene associated with Macrocephaly, Dysmorphic Facies, and Psychomotor Retardation is HERC1 (HECT And RLD Domain Containing E3 Ubiquitin Protein Ligase Family Member 1). Affiliated tissues include bone, and related phenotypes are tall stature and high palate

UniProtKB/Swiss-Prot : 75 Macrocephaly, dysmorphic facies, and psychomotor retardation: An autosomal recessive syndrome characterized by large head and somatic overgrowth, intellectual disability, and facial dysmorphism. Seizures, hypotonia and ataxic gait are observed in some patients.
