"Young Cayson suffers from a genetic disorder called Williams syndrome, also known as Williams-Beuren syndrome, a condition that causes loss of genes that can affect development. In Cayson’s particular case, one of the missing genes causes a loss of elastin in blood vessels and other tissues, which gives him a heart condition, as the missing gene causes blood vessels to narrow. Not all children with Williams syndrome suffer from the same heart condition. However, the McClures find hope by believing it’s, “in the Lord’s hands. We take it day-by-day,” says mother Tameran. Cayson had a stint put in his heart the week before Thanksgiving that will stay in for the rest of his life, and was still in the hospital on Thanksgiving, so the mother remarked they felt, “lucky he was well enough to go.”"
