Summaries for Kleefstra Syndrome 1

OMIM® : 57 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. (610253) (Updated 05-Mar-2021)

MalaCards based summary : Kleefstra Syndrome 1, also known as 9q subtelomeric deletion syndrome, is related to kleefstra syndrome and kleefstra syndrome due to a point mutation, and has symptoms including seizures An important gene associated with Kleefstra Syndrome 1 is EHMT1 (Euchromatic Histone Lysine Methyltransferase 1). Affiliated tissues include tongue, heart and testis, and related phenotypes are intellectual disability and dysphasia

Disease Ontology : 12 A syndrome that is characterized by 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 and that has material basis in a microdeletion in the chromosome region 9q34.3 or by a point mutation in the EHMT1 gene located in that region.

UniProtKB/Swiss-Prot : 73 Kleefstra syndrome 1: A form of Kleefstra syndrome, an autosomal dominant disease characterized by variable mental retardation, psychomotor developmental delay, seizures, behavioral abnormalities, and facial dysmorphisms. KLEFS1 patients additionally manifest brachy(micro)cephaly, congenital heart defects, and urogenital defects.
