Syndromic congenital diarrhoea: new SPINT2 mutation identified in the UAE.


ABSTRACT: We are reporting a new mutation in the SPINT2 gene (c.443G>A (p. Arg148His)) that explains the association of choanal atresia with congenital sodium diarrhoea (CSD) in an Emirati family in the Middle East. To our knowledge, this mutation is neither listed in a mutation database nor described in the literature. Similar to other patients with CSD associated with SPINT2, this child remains dependent on parenteral nutrition for fluids and nutritional support resulting in failure to thrive. The determination of the molecular basis of syndromic CSD will facilitate prenatal and postnatal diagnosis of patients and will contribute to counselling of affected families, especially in areas like the UAE where consanguineous marriages are not uncommon.
