BACKGROUND Combined pituitary hormone deficiency 3(CPHD3;OMIM:221750)is caused by mutations within the LHX3 gene(OMIM:600577),which located on the subtelomeric region of chromosome 9 at band 9q34.3,has seven coding exons and six introns.LIM homeobox(LHX)3 protein is the key regulator of pituitary development in fetal life.CASE SUMMARY We have diagnosed and treate an 11-year-old boy with combined pituitary hormone deficiency(CPHD).The main clinical manifestations were pituitary hormone deficiency,hydrocele of the tunica vaginalis,pituitary dwarfism,gonadal dysplasia,micropenis,clonic convulsion,and mild facial dysmorphic features.We collected peripheral blood from the patient,the patient's older brother,as well as their parents,and sequenced them by using high-throughput whole-exosome sequencing,which was verified by Sanger sequencing.The results showed that there were two compound heterozygous variants of c.613G>C(p.V205L)and c.220T>C(p.C74R)in the LHX3 gene.c.613G>C(p.V205L)was inherited from his mother and c.220T>C(p.C74R)from his father.His brother also has both variants and symptoms.CONCLUSION This study reported ununreported genetic mutations of LHX3,and recorded the treatment process of the patients,providing data for the diagnosis and treatment of CPHD. 展开更多
