Once the IKBKG pathogenic variant has been identified in an affected family member, prenatal testing for a pregnancy at increased risk and preimplantation genetic diagnosis are possible.


An affected male with somatic mosaicism that includes the germline may transmit the IKBKG pigmentsria variant to female offspring all daughters inheriting the pathogenic variant would be affected ; male offspring are not at risk of inheriting the pathogenic variant.

The girls are still undergoing investigations on the cardiovascular system, as preliminary reports indicate some cardiac rhythmic anomalies Table. Targeted analysis for the common Nonetheless, skin biopsy may be helpful in confirming the diagnosis in a female with borderline or questionable findings in whom molecular incontnencia testing has not identified a pathogenic variant. The discoloration sometimes fades with age. June 8, ; Last Update: Discolored skin is caused by excessive deposits of melanin normal skin pigment.

The recurrent pathogenic variant in individuals with IP is an Survival of male patients with incontinentia pigmenti carrying a lethal mutation can be explained by somatic mosaicism or Klinefelter syndrome.

Pedigree patterns suggested X-linked dominance with lethality in the male. Incontinentia pigmenti is a rare X-linked dominant condition characterized by cutaneous, neural, ocular and dental manifestations. X-chromosome inactivation studies to look for evidence of skewing can be helpful in identifying female relatives who have an IKBKG pathogenic variant that cannot be identified in the proband.
