Neu–Laxova's Syndrome: A Case Report of a Fetus with Novel Mutation in PHGDH Gene and a Literature Review

Abstract

Neu–Laxova's syndrome (NLS) is a rare group of congenital malformations comprising intrauterine growth retardation (IUGR), central nervous system malformations, microcephaly, facial anomalies, ichthyosis, generalized edema, limb abnormalities, polyhydramnios, and perinatal death. We hereby report a fetus at 25 weeks' gestation with IUGR, facial and limb anomalies, and smooth brain detected on antenatal ultrasound and magnetic resonance imaging of fetus and confirmed by autopsy. Next-generation sequencing analysis identified a novel homozygous missense mutation in PHGDH gene. Only 35 cases of NLS with genetic etiology have been reported. This is the first case report of mutation in PHGDH from India.

Keywords

Neu–Laxova's syndrome - limb anomalies - PHGDH gene - serine biosynthesis defect
