IFNL3 and Ventriculomegaly: In addition, a significantly higher proportion of individuals carrying heterozygous (C/T) genotype at IL28B rs 12979860 was observed among infants with cCMV and ventriculomegaly compared with those with normal ventricular size (53.5% vs. 31.8%; OR = 2.46, 95%CI, 1.03–5.90; p = 0.04) in the most fitted genetic model, being the overdominant model (Table 6).
