Glucose-6 phosphatase catalytic subunit 3 (G6PC3) mutations are classified as SCN type 4 (SCN4), which is presented with multiple organ involvements such as congenital heart defects, urogenital abnormalities, superficial vein visibility, in addition to severe neutropenia (absolute neutrophil count less than 0.5 × 109/L) [4, 5]. Here, G6PC3 is linked to neutropenia.
