Summaries for Smith-Kingsmore Syndrome

OMIM : 57 Smith-Kingsmore syndrome is a rare autosomal dominant syndromic intellectual disability syndrome characterized by macrocephaly, seizures, umbilical hernia, and facial dysmorphic features including frontal bossing, midface hypoplasia, small chin, hypertelorism with downslanting palpebral fissures, depressed nasal bridge, smooth philtrum, and thin upper lip (Smith et al., 2013; Baynam et al., 2015). (616638)

MalaCards based summary : Smith-Kingsmore Syndrome, also known as macrocephaly-intellectual disability-neurodevelopmental disorder-small thorax syndrome, is related to actinic keratosis and neuroblastoma. An important gene associated with Smith-Kingsmore Syndrome is MTOR (Mechanistic Target Of Rapamycin Kinase), and among its related pathways/superpathways is mTOR signaling pathway. Affiliated tissues include lung, skin and colon, and related phenotypes are macrocephaly and hypertelorism

UniProtKB/Swiss-Prot : 75 Smith-Kingsmore syndrome: An autosomal dominant syndrome characterized by intellectual disability, macrocephaly, seizures, umbilical hernia, and facial dysmorphic features.
