“…For single nucleotide variants (SNV), the sequencing raw data was processed by DRAGEN platform (SW: 05.021.595.3.7.5) (Illumina Inc., USA). All obtained variants from Variant Call Format (VCF) file were further filtered by a panel of PAH-related genes including 16 WSPH-listed [ BMPR2, KCNK3, EIF2AK4, KLF2, ACVRL1, SMAD1, AQP1, SMAD4, ATP13A3, SMAD9, TBX4, SOX17, CAV1, KCNA5, BMPR1B, GDF2 ( 23 ) and ENG ] ( 2 ) and 14 non-WSPH-listed genes [ ABCA3 ( 18 , 24 ) , NOTCH1 ( 25 , 26 ) , NOTCH2 ( 27 , 28 ) , NOTCH3 ( 15 , 29 ) , ABCC8 ( 11 , 12 ) , BMP10 ( 30 , 31 ) , FBLN2 ( 32 ) , JAG1 ( 33 ) , PTGIS ( 34 ) , PDGFD ( 32 ) , GGCX ( 35 ) , SMAD5 ( 36 , 37 ) , KLK1 ( 35 ) and TopBP1 ( 26 , 38 )]. Those variants with read depth <30x were filtered out.…”
