We noted that LRIG2 SVA dosage was associated with contrasting effects on PPM1J expression in our ΔSVA SH-SY5Y cell lines and in the NABEC data, and postulate that this may be due to phenotypic differences between SH-SY5Y neuroblastoma cells and the frontal cortex tissue collected in NABEC samples. Here, LRIG2 is linked to neuroblastoma.
