This is because in the common thinking model, the multiple disease symptoms are tending to be considered as the presentation of a complicated “syndrome”. This thinking pattern also confine their way of filtering pathogenic mutations. The real pathogenic mutations might be ignored due to not covering all disease presentations. Here we report a case of a girl who was suffered from spherocytosis and antley-bixler syndrome with genital anomalies and disordered steroidogenesis. She remained undiagnosed even after gene detection before. However, after doing the Next-generation sequencing and the analysis of the sequencing data, we identified two mutations, c.2978T>A in ANK1 and mutation c.1370G>A in POR gene. Our findings and experience in the diagnosis could expand the thoughts in clinical and genetic diagnosis of patients with multiple systems involved.
