PPFIBP1 and neurodevelopmental disorder: The results identified one potential KS candidate gene (TSPAN11), seven candidate genes for the neurodevelopmental disorder (TM7SF3, STK38L, ARNTL2, ERGIC2, TMTC1, DENND5B, and ETFBKMT), and four candidate genes for KS with ID (INTS13, REP15, PPFIBP1, and FAR2).
