Sufficient evidence for an association with growth hormone deficiency, however limited evidence for intellectual disability. ID and growth hormone deficiency identified in a single family with 26 Ala repeats (11 Ala expansion). 22 Ala repeats (7 Ala expansion) has been identified in two families with hypopituitarism (without ID). Mouse model demonstrates that mechanism of disease is polyAlanine tract leading to a loss of function of the protein,
