Background: Mutations in CYP21A2 are the most common cause of congenital adrenal hyperplasia (CAH). Even though disease linked mutations are rarely classified as founder, in this study, we describe a novel founder mutation, c.2T>C (p.M1?), inactivating the translation initiation codon.Objective and Hypotheses: We aimed to investigate genotype–phenotype correlation and population based origin of this novel mutation in CAH patients with 2...

Background: Raine syndrome (RS) also known as lethal osteosclerotic bone dysplasia, is a rare autosomal recessive bone disorder. Most of patients with RS die within the first days or weeks of life due to pulmonary hypoplasia. The causative gene FAm20C is located on chromosome 7p22.3. FAm20C is one of the genes that regulate phosphate production. Here, we present a case of RS with hypophosphatemic rickets and a new mutation in FAm2</s...
