TREX1 and Aicardi-Goutieres syndrome: Another autosomal recessive condition that clinically mimics pseudo-TORCH syndrome is Aicardi–Goutieres syndrome (AGS), which is caused by harmful mutations in at least seven genes involved in encoding enzymes involved in the intracellular metabolism of nucleic acids, and these genes are as follows: IFIH1, RNASEH2C, RNASEH2B, RNASEH2A, ADAR, TREX1, or SAMHD1 [2, 3].
