IKBKG and incontinentia pigmenti: In our current IP cohort, we detected the IKBKG exon 4‐10 common deletion in 13 patients (03f, 05f, 06f, 08f, 13f, 14f, 16f, 18f, 21f, 22f, 28f, 29f, and 30f; Figure 1a) which was a prevalence (detection rate) of 43.3% among the total series of 30 patients (Table 1).
