Introduction Pseudohypoparathyroidism type 1a is caused by GNAS mutations leading to target organ resistance to multiple hormones rather than parathyroid hormone, resulting not only in hypocalcemia, but also in Albright's hereditary osteodystrophy phenotype. Materials and Methods DNA sequencing of the GNAS gene identified a novel heterozygous mutation in peripheral blood leukocytes in the family presented in this case report. Results We present a case of a 25-year-old woman with pseudohypoparathyroidism type 1a admitted with seizures, whose family presents an autosomal dominant transmission of a novel heterozygous GNAS mutation (c.524_530+3del). Conclusion Pseudohypoparathyroidism type 1a is mostly caused by inactivating GNAS mutations that have been gradually reported in the literature that lead to a typical and complex clinical phenotype and resistance to multiple hormones. The deletion caused by the mutation identified in the presented case has not been reported previously.
