brain malformations with or without urinary tract defects
Findings
No curated finding names brain malformations with or without urinary tract defects yet. Everything below is reference data from Mondo, HPO and GenCC, not evidence about what affects it.
Definition
A brain disorder caused by pathogenic variants in NFIA that is characterized by developmental delay, corpus callosum agenesis/hypoplasia and craniofacial dysmorphism, such as macrocephaly (caused by hydrocephalus or ventriculomegaly), low-set ears, anteverted nostrils and micrognathia. Urinary tract defects (e.g. vesicoureteral reflux, urinary incontinence) are also frequently associated. Other reported variable manifestations include hypotonia, tethered spinal cord, Chiari type I malformation and seizures.
