ZGRF1 and nervous system disorder: LOC107987057 or C9orf72 variants have been linked to several neurological disorders, including ASD43. However, Chi-square analyses showed that the frequencies of these 4 variants LOC107987057 rs2814707, ZGRF1 rs61745597, ZGRF1 rs76187047 and SCN9A rs12478318 observed in our study are not significantly different from the East Asian population in the 1000 Genome Project 30x (p-value = 0.27, 0.82, 0.82, and 0.21 respectively) (Sup.
