Abstract
- Abstract Background Pediatric pulmonary hypertension (PH) is a serious and rare disease that is often derived from genetic mutations. Kabuki syndrome (KS) is a chromosomal abnormality disease that has its origin in the mutation of lysine methyltransferase 2D(KMT2D). Recent evidence has shown that KMT2D mutations are associated with pediatric pulmonary disorders. However, the relationship between the clinical courses of PH and the KMT2D mutation is reported in extremely few cases. Therefore, in this paper, a case was presented and previous literature was reviewed for better understanding of the correlation between pediatric PH and KMT2D mutations. Case presentation A 3-year-old girl was transferred to our center for severe cough, shortness of breath, fatigue and fever. Physical examination revealed facial deformities and growth retardation. Echocardiography showed a small atrial septal defect (ASD), and right heart catheterization indicated a significant increase in pulmonary vascular pressure and resistance. The genetic test suggested that she had a KMT2D gene mutation. The patient was finally diagnosed with KS. She was given targeted drugs to reduce pulmonary vascular pressure, but the effect was unsatisfactory. Conclusions KS can be complicated with multiple organ malformations and dysfunction. With the progress of next generation sequencing, an increasing number of new phenotypes related to KMT2D mutations have been reported. A bold hypothesis is proposed in this article, that is, PH may be a new phenotype associated with KMT2D mutations. It is suggested that KS and PH should be differentiated from each other to avoid delayed diagnosis and treatment in clinical practice. There is no specific drug for KS treatment. The prognosis of children with inherited PH is usually poor, and lung transplantation may increase their survival rates.
