Neu-Laxova Syndrome Type 2

NLS2


Presentation

  • Weiner, Bernard Gonik, Caroline Crowther, and Stephen Robson present an evidence-based approach to the available management options, equipping you with the most appropriate strategy for each patient.[books.google.de]
  • Brain malformations may be present as well. Genetics This disorder has a transmission pattern consistent with autosomal recessive inheritance. Homozygous or compound heterozygous mutations in the PSAT1 gene (9q21.2) are responsible.[disorders.eyes.arizona.edu]

Reduced Fetal Movement
  • The tight skin of the fetus reduces fetal movement leading to failure of swallowing and contractures are development. [1] The exact cause for this condition has not been established, but various theories have been postulated.[ijpmonline.org]
  • These may include severely delayed growth (intrauterine growth retardation); excessive fluid in the thin-walled membrane (amniotic sac) surrounding the fetus during pregnancy (polyhydramnios); abnormally reduced fetal movements; a short umbilical cord[rarediseases.org]
Deformed Limbs
  • Affected patients have abnormal craniofacial features, microcephaly, intrauterine growth retardation, ichthyosis, flexion deformities, limb malformations, and edema of the hands and feet.[malacards.org]
Swelling of Hand
  • Group II: massive swelling of hand and feet, ichthyosis, undermineralized bones and Group III: hypoplastic digits, severe ichthyosis, short limbs and stick-like long bones.[ijpmonline.org]

Treatment

  • […] time, but L-serine supplementation may prove to be an effective treatment in the future if the NLS is found early during a pregnancy. [3] [4] Last updated: 1/29/2017[rarediseases.info.nih.gov]

Prognosis

  • Treatment and prognosis The prognosis is very poor with most fetuses undergoing intrauterine death and the remainder not surviving the early neonatal period. Promoted articles (advertising)[radiopaedia.org]
  • Treatment [ edit ] Serine and glycine supplementation has shown tentative benefits in those with related serine biosynthesis defects and milder forms of NLS [6] Prognosis [ edit ] The prognosis is poor; affected individuals are either stillborn or die[en.wikipedia.org]

Etiology

  • A careful search for previously reported genetic causes of fetal hydrops indicated 64 different etiologies.[pediatrics.aappublications.org]
