Abstract
Peripheral pulmonary arterial stenosis (PPAS) is commonly observed in paediatric patients with associated congenital heart disease or systemic congenital syndromes, such as tetralogy of Fallot and Williams syndrome [1]. Meanwhile, isolated PPAS without other structural heart disease or systemic congenital syndromes is primarily reported in adulthood [2]. Recent genetic analyses have revealed that four cases of isolated PPAS in adulthood were homozygous for the ring finger protein 213 (RNF213) p.Arg4810Lys variant (also referred to as G to A alteration of rs112735431 and NM_001256071.3:c.14429G>A) [3]. RNF213 p.Arg4810Lys is a genetic determinant in moyamoya disease (MMD) in East Asians [4]. This genetic variant is unique to East Asians and is reported to have a frequency of approximately 0.8% in the general Japanese population [5, 6]. However, its prevalence in adult patients with isolated PPAS remains unknown. The RNF213 p.Arg4810Lys mutation is closely linked to the development of PPAS. Stent deployment might be a promising treatment option, but further investigation would be warranted. https://bit.ly/40t8Gmz
