Spinal Muscular Atrophy with Respiratory Distress Type 1 (SMARD1): Are We Diagnosing Yet?

Abstract

The spectrum of disorders associated with the IGHMBP2 (immunoglobulin μ-binding protein 2) gene pathogenic variants is still unknown. In this case report, we discussed an interesting case of genetically confirmed spinal muscular atrophy with respiratory distress type 1 (SMARD1) with atypical sparing of the diaphragm, thus expanding the phenotypic spectrum of this intriguing disorder and also highlight the importance of reconsidering the selection criteria for considering IGHMBP2 pathogenic variants.

Keywords

spectrum - IGHMBP2 - spinal muscular atrophy with respiratory distress type 1 - Charcot–Marie–Tooth type 2S - criteria
