Autosomal recessive distal spinal muscular atrophy 1 (or spinal muscular atrophy with respiratory distress type 1, or distal spinal muscular atrophy 1)[1] is a form of spinal muscular atrophy.
It is characterized by intrauterine growth retardation, often premature birth, foot deformity, and a characteristic pattern of breathing (the stomach draws inward with inspiration) that indicates weakness of the diaphragm; in classic SMA type 1 the diaphragm is strong and the stomach prominently protrudes with inspiration (paradoxic breathing pattern).
It is associated with IGHMBP2.[2][3]
