(2011) identified a heterozygous 1-bp deletion (c.106delG, NM_022912.2) in exon 3 of the REEP1 gene, predicted to result in a frameshift and premature termination (Val36SerfsTer4). The patient had a similarly affected father and brother, but both were deceased and unavailable for study. Patient-derived skin fibroblasts showed abnormal mitochondrial morphology with elongated tubules, suggesting fission/fusion alterations. Muscle biopsy from the patient showed alteration mitochondrial respiration with decreased oxygen consumption. (less)
