It’ll soon be here!

Join us for #WorldPVNHday on August 7th and help us raise awareness for all affected by PVNH, GMH and SBH by requesting illuminations and proclamations around the world.

Thank you to our PVNH Community, and to all our World PVNH Day illumination partners and allies for their ongoing support. We couldn’t do it without you!

You can view photos and read stories on our Facebook, Instragram and Twitter accounts (@PVNHsupport) and here.

PVNH stands for Periventricular Nodular Heterotopia and is sometimes referred to as Grey (or Gray) Matter Heterotopia (GMH) because it is the most common form of Grey Matter Heterotopia. Both fall under the Neuronal Migration Disorders or Malformations of Cortical Development categories. Another acronyms for it is PNH, usually seen in some medical journals.  It is a rare neuronal migration disorder which is also known as  PH, BPH, BPNH, PVH and subependymal heterotopia. The most common form is X-Linked PVNH (formerly called PVNH4), and is caused by a FLNA gene deficiency.  PVNH can sometimes happen in conjunction with other disorders such as Ehlers-Danlos Syndrome, or Polymicrogyria. In addition to several gene variants, chromosomal abnormalities can cause PVNH.

There are other forms of neuronal heterotopia disorders, the such as Subcortical Band Heterotopia (SHB), also known as Double Cortex.

PVNH Support & Awareness proudly supports more than 880+ families  with PVNH, GMH and SBH in 40 countries,  and collaborates with world specialists, researchers, rare disease organisations and other groups of interests to make a positive impact in the lives of those affected by neuronal heterotopia disorders.

PVNH Support  & Awareness TM is an international patient organization of global reach uniting families and which collaborates with PVNH genetic leaders, specialists, researchers. We also have alliances with some of the most outstanding rare disease advocates worldwide. PVNH Support  & Awareness TM was founded in November 2009 as a legacy for Yolaine Dupont’s daughter, Ella Dupont Bedassie. Ella was 7 months and 20 days when she passed away from respiratory failure brought on by what doctors did not know at the time was a rare disease: X-Linked Periventricular Nodular Heterotopia. The FLNA gene deficiency at cause is familial, with both Yolaine and her late mom also affected by the rare disorder, a fact that was unknown until Yolaine demanded and pursued answers.

PVNH Support  & Awareness TM exists to give affected patients and families a gathering place, educate patients, families as well as medical and other communities about PVNH and other neuronal heterotopia disorders, and facilate and drive research.

This is for Ella, so that her death is not in vain and her memory keeps on living with each affected family receiving the support they deserve, and treatment their loved ones need.
