GARD : ²⁰ Fowler's syndrome mainly affects young women and leads to the inability to empty the bladder ( urinary retention ). Many women have no other symptoms, although some women experience stomach pain. Fowler's syndrome is caused by spasms of the external urethral sphincter, a band of muscle that opens and closes at the exit of the bladder. The cause is unknown, but it has been known to occur after a surgical procedure, childbirth, opiate use, or other medical condition. Fowler's syndrome is difficult to diagnose, but many women with Fowler's syndrome have abnormal electrical activity on a specialized test called concentric needle electromyography. Fowler's syndrome is most often treated by using a device placed inside the body that helps stimulate the bladder.

MalaCards based summary : Proliferative Vasculopathy and Hydranencephaly-Hydrocephaly Syndrome, also known as encephaloclastic proliferative vasculopathy, is related to hydranencephaly and hydrocephalus, congenital, 1. An important gene associated with Proliferative Vasculopathy and Hydranencephaly-Hydrocephaly Syndrome is FLVCR2 (FLVCR Heme Transporter 2), and among its related pathways/superpathways are Biosynthesis of cofactors and Porphyrin and chlorophyll metabolism. The drugs Acetylcholine and abobotulinumtoxinA have been mentioned in the context of this disorder. Affiliated tissues include spinal cord, retina and brain, and related phenotypes are agenesis of corpus callosum and hydrocephalus

Disease Ontology : ¹² A syndrome characterized by hydranencephaly, glomeruloid vasculopathy of the central nervous system and retinal vessels, diffuse clastic ischemic lesions of the brain stem, basal ganglia, and spinal cord with calcifications, and fetal akinesia with arthrogryposis that has material basis in homozygous or compound heterozygous mutation in FLVCR2 on chromosome 14q24.3.

OMIM® : ⁵⁷ The proliferative vasculopathy and hydranencephaly-hydrocephaly syndrome is a rare, autosomal recessive, usually prenatally lethal disorder characterized by hydranencephaly, a distinctive glomerular vasculopathy in the central nervous system and retina, and diffuse ischemic lesions of the brain stem, basal ganglia, and spinal cord with calcifications. It is usually diagnosed by ultrasound between 26 and 33 weeks' gestation (summary by Meyer et al., 2010). Rarely, affected individuals may survive, but are severely impaired with almost no neurologic development (Kvarnung et al., 2016). (225790) (Updated 05-Apr-2021)

KEGG : ³⁶ Proliferative vasculopathy and hydranencephaly-hydrocephaly syndrome (PVHH), also known as Fowler syndrome, is an autosomal-recessively inherited prenatal lethal disorder of brain angiogenesis, resulting in abnormally thickened and aberrant perforating vessels leading to hydranencephaly. Mutations and a large deletion in the FLVCR2 gene have been revealed in the families with Fowler syndrome. FLVCR2 encodes a transmembrane transporter of the major facilitator superfamily (MFS) hypothesized to be involved in regulation of growth, calcium exchange, and homeostasis.

UniProtKB/Swiss-Prot : ⁷² Proliferative vasculopathy and hydranencephaly-hydrocephaly syndrome: A rare prenatally lethal disorder characterized by hydranencephaly, a distinctive glomerular vasculopathy in the central nervous system and retina, and diffuse ischemic lesions of the brain stem, basal ganglia, and spinal cord with calcifications. Hydranencephaly is a condition where the greater portions of the cerebral hemispheres and corpus striatum are replaced by cerebrospinal fluid and glial tissue.
