LWT13 - An international group of families who have had a child diagnosed with Trisomy 13 – Patau Syndrome. Whether they are: on the prenatal journey...have a child living presently...or have a child who has died and still grieving. This is an amazing site where families through their own grief and pain, reach out to help others on this very unique journey with Trisomy 13. All these families have lived and are living with a Trisomy 13 diagnosis and the reality of how it changes lives.
