Summaries for Neu-Laxova Syndrome 1

NIH Rare Diseases : 50 neu laxova syndrome (nls) is a genetic disorder affecting many parts of the body. babies born with nls usually grow poorly during the pregnancy (intrauterine growth restriction). at birth, they will be small (low birth weight and short in length) and their facial features are usually different and distinct. the babies may have a small head (microcephaly), sloping forehead, and widely spaced eyes (hypertelorism). babies with nls may also have extra fluid (edema) in their hands and feet, brain abnormalities, and rigid, stiff muscles. other birth defects may affect the baby's arms, legs, skin, genitals, kidneys, and heart. not every baby with nls will have every sign or symptom of nls. neu laxova syndrome (nls) is caused by changes or mutations in one of three different genes, phgdh, psat1, psph. the mutations cause too little l-serine (an amino acid) to be made. there must be a mutation in both copies of one of these genes, which means nls is inherited in an autosomal recessive manner. nls can be diagnosed both prenatally by an ultrasound or after birth. the diagnosis is suspected by signs and symptoms, but may be confirmed by genetic testing (prenatally by chorionic villi sampling (cvs) or amniocentesis; after birth by genetic blood test). there is no cure or treatment for nls at this time, but l-serine supplementation may prove to be an effective treatment in the future if the nls is found early during a pregnancy.  last updated: 1/29/2017

MalaCards based summary : Neu-Laxova Syndrome 1, also known as neu-laxova syndrome, is related to neu-laxova syndrome 2 and noonan-like/multiple giant cell lesion syndrome, and has symptoms including microcephaly, micrognathia and hypertelorism. An important gene associated with Neu-Laxova Syndrome 1 is PHGDH (Phosphoglycerate Dehydrogenase), and among its related pathways/superpathways are Carbon metabolism and One carbon pool by folate. The drugs Dopamine and Mazindol have been mentioned in the context of this disorder. Affiliated tissues include lung, skin and eye.

UniProtKB/Swiss-Prot : 71 Neu-Laxova syndrome 1: A lethal, autosomal recessive multiple malformation syndrome characterized by ichthyosis, marked intrauterine growth restriction, microcephaly, short neck, limb deformities, hypoplastic lungs, edema, and central nervous system anomalies including lissencephaly, cerebellar hypoplasia and/or abnormal/agenesis of the corpus callosum. Abnormal facial features include severe proptosis with ectropion, hypertelorism, micrognathia, flattened nose, and malformed ears.
