|a Objective: To investigate the clinical features and genetic characteristics of cases with NBAS gene defects. Method: Characteristics of clinical materials, immunological data and gene mutation of the first case in China with NBAS gene mutation were retrospectively analyzed. The related literature was searched by using search terms'NBAS'. Result: A 2-year-four-month old girl, was admitted due to 'fever and pallor for one day'. There was an intrauterine growth retardation at her fetal stage. Since her birth, she had suffered from recurrent infections and development delay was accompanied by persistent liver dysfunction. Her head circumference and height were 43.5 cm and 60 cm, respectively. She seemed pale. She had progeroid appearance with loose skin, sparse hair, proptosis and low-set ears. The cranial suture did no close and the anterior fontanel was about 6 cm×5 cm. Abdominal palpation showed that the liver was 2 cm below the right costal margin, and the spleen was 1.5 cm below the left rib. Both alanine aminotransferase(100-1 991 IU/L) and aspartate aminotransferase (191-1 367 IU/L) were persistently abnormal. Visual evoked potentials and fundus examination revealed optic nerve atrophy. Bone mineral density assessment showed osteoporosis. The IgG level was 2.0 g/L (3.41-19.6) and absolute count of CD19(+)B cells was 231.27/μl (608.8-2 167.7) . Her hemoglobin level was 53 g/L. Bone marrow smear showed serious hypoplasia in erythroid cell. The gene sequencing results showed NBAS gene c.5741C> T, pR1914H and c.6496-6497insA, p.S2166Ffs* 2 compound heterozygous mutations. A total of 8 literatures were collected including 57 cases with NBAS gene homozygous or compound heterozygous mutation. These 57 cases were characterized by short stature(88%, 50/57) , Pelger-Huët anomaly (75%, 43/57) , skeletal dysplasia (74%, 42/57), optic nerve atrophy (72%, 41/57), abnormality of liver enzymes or acute liver failure (42%,24/57), abnormalities of immune system(19%, 11/57), development delay of mental, language or sports(11%, 6/57). Other clinical manifestations such as progeroid appearance, proptosis and hypotonia were also common. NBAS gene c.5741G>A homozygous mutation accounted for 61% (35/57) cases. Conclusion: Cases with NBAS gene defects often manifests as short stature, optic nerve atrophy, Pelger-Huët anomaly, skeletal dysplasia, recurrent infections, abnormality of liver enzymes, progeroid appearance, proptosis, hypotonia and immunodeficiency. Gene sequencing analysis showed NBAS gene homozygous or compound heterozygous mutations, and homozygous mutation of c.5741G>A was most common
