Summaries for Lujan-Fryns Syndrome

About this section
NIH Rare Diseases:45 Lujan syndrome is a condition characterized by intellectual disability, behavioral problems, poor muscular tonus (hypotonia) and certain physical features like a tall and thin body and a large head (macrocephaly) with a thin face with distinctive facial features (prominent top of the nose, short space between the nose and the upper lip (philtrum), narrow roof of the mouth (palate), crowded teeth and a small chin (micrognathia). most of the cases occur in males. it is caused by an alteration (mutation ) in the med12 gene. the med12 gene mutation changes a single protein building block (amino acids ) in the med12 protein which helps regulate gene activity and is involved in many aspects of early development. however, it is unclear how the mutation affects development and leads to the cognitive and physical features of lujan syndrome. treatment includes early individualized education; physical therapy, occupational therapy, and speech therapy for developmental delays; routine management of behavior problems, seizures, and other problems that may exist. the lujan syndrome and the fg syndrome type 1 (fgs1) are the main conditions of a group of disorders known as med12-related disorders because they are all caused by mutations in the same gene. last updated: 10/15/2015

MalaCards based summary: Lujan-Fryns Syndrome, also known as marfanoid habitus, mild general hypotonia, hypernasal voice, normal testicular size and distinct craniofacial anomalies, is related to fryns syndrome and lujan syndrome, and has symptoms including abnormality of the genitourinary system, open mouth and high palate. An important gene associated with Lujan-Fryns Syndrome is MED12 (Mediator Complex Subunit 12), and among its related pathways is Thyroid hormone signaling pathway. Related mouse phenotype limbs/digits/tail.

UniProtKB/Swiss-Prot:67 Lujan-Fryns syndrome: Clinically, Lujan-Fryns syndrome can be distinguished from Opitz- Kaveggia syndrome by tall stature, hypernasal voice, hyperextensible digits and high nasal root.
