Mutations in the KIAA1279 gene (OMIM #609367) have been identified in patients with GOSHS and homozygous nonsense mutations have been reported in 10 affected individuals in two families. The KIAA1279 gene maps to 10q22.1 and is likely important in both enteric and central nervous system development as it is highly expressed in heart, brain, reproductive, spinal cord regions. It has 7 exons, spanning 28 kb, with 2 tetratricopeptide repeats (TPR).
