ABSTRACT
BACKGROUND:
NFIA gene (OMIM*600727) has been shown to be associated with a syndrome of central nervous system malformations (corpus callosum and ventriculomegaly) with or without urinary tract defects(BRMUTD) (OMIM#613735) with a low incidence. METHODS ANDRESULTS:
We presented the clinical data of a 3-month-old Chinese infant with clinical features such as thin corpus callosum, ventriculomegaly, development delay, and dysmorphic features (macrocephaly, hypertelorism, slightly pointed chin, broad forehead, and large ears). Genomic DNA was extracted for Trio Whole Exome Sequencing. Preliminary genetic tests revealed one de novo heterozygous nonsense mutation c.220 C>T (p.Arg74Ter) of the NFIA gene (NM_005595).CONCLUSION:
Genetic DNA sequencing is a crucial method for diagnosing BRMUTD. This approach enriches the genotype and spectrum of BRMUTD syndrome and the outcome of the patient.
