Most patients carry missense mutations in the STIM1 Ca<jats:sup>2+<\/jats:sup>-sensing EF-hands or in the CC1 domain implicated in ORAI1 activation.<\/jats:p>\n               <jats:p>Here we report the first STIM1 deletion in a patient with moderate TAM\/STRMK phenotype encompassing exercise-induced muscle weakness, elevated creatine kinase levels, asplenia and transient thrombocytopenia. The c.702_725del mutation occurred de novo and is predicted to involve the deletion of eight amino acids between EF-hands and the CC1 domain. We conducted a series of functional experiments in mouse and human cells lines and provided the evidence that the in-frame deletion causes constitutive STIM1 clustering and ORAI1 recruitment, resulting in profuse extracellular Ca<jats:sup>2+<\/jats:sup> entry and major nuclear translocation of the transcription factor NFAT1. Overall, this work illustrated the pathogenicity of the STIM1 in-frame deletion at different levels of the SOCE pathway and provided a molecular diagnosis for the affected
