Liam, the lion-hearted toddler, needs a new kidney. But he has courage. William and Vanessa Houck’s 16-month-old suffers from the rare Eagle-Barrett syndrome — sometimes referred to as prune-belly syndrome — and is in need of a kidney transplant, they said. The disease, which affects about one in 40,000 births — mostly in boys — forces Liam to spend 12 hours a day on dialysis and three hours a day being fed though a tube. Vanessa Houck said that despite all the discomfort, her child is “the happiest and is crazy about lions.” The word “roar” was among the first he spoke. William Houck is a Marine captain who flies a C-130 Hercules. Vanessa was an Air Force tanker pilot but received a hardship separation to take care of the couple’s son. The couple has insurance through the military TRICARE program, but recently learned the remaining out-of-pocket expenses for their baby’s lifesaving operation could reach $50,000. As a result, Point Loma’s Cup of Yo yogurt shop in the Fresh & Easy shopping center on Catalina Boulevard has decided to help raise money for Liam. Veronica Eckert’s (Yo’s co-owner) father is a liver transplant recipient, which prompted her to donate some of the store’s profit and to begin collecting donations for the child. To date, five people have offered to donate a kidney to Liam and thousands of dollars have already been raised.   For more information, call (619) 885-0700, or visit the Children’s Organ Transplant Association website at www.cotaforliamh.com. Donations may also be made directly at Cup of Yo, located at 955 Catalina Blvd.
