Kleefstra syndrome 1

Preferred Label : Kleefstra syndrome 1;

Symbol : KLEFS1;

CISMeF acronym : KLEFS1;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : 9q- syndrome; 9q subtelomeric deletion syndrome; Chromosome 9q34.3 deletion syndrome;

Description : Submicroscopic subtelomeric deletions of chromosome 9q are associated with a recognizable mental retardation syndrome (Harada et al., 2004; Iwakoshi et al., 2004; Stewart et al., 2004; Neas et al., 2005). Common features in patients with 9q subtelomeric deletion syndrome are severe mental retardation, hypotonia, brachy(micro)cephaly, epileptic seizures, flat face with hypertelorism, synophrys, anteverted nares, everted lower lip, carp mouth with macroglossia, and heart defects.;

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in the euchromatic histone methyltransferase-1 gene (EHMT1, 607001.0001);

Prefixed ID : #610253;
