Vormittag W, Ensinger C, Roff M: Cytogenetic and dermatoglyphic findings in a familial case of hypomelanosis of Ito (incontinentia pigmenti achromians). Clin. Genet. 41:309-314, 1992. [PubMed: 1623628 Hypomelanosis of Ito is believed to be due to chromosomal mosaicism and sporadic mutations. It is not an inherited disorder as the chromosomal defect occurs after conception. The specific gene (s) is most likely a balanced translocation of Xp21.2. How is the diagnosis of hypomelanosis of Ito made Hypomelanosis of Ito (OMIM 300337) is a phenotype related to chromosomal mosaicism. Another important differentiation is that in individuals with IP the hyperpigmented areas are abnormal, whereas in hypomelanosis of Ito hypopigmentated areas are abnormal. In individuals with chromosomal mosaicism, it can often be difficult to distinguish which. The individual with the MTOR gene mutation also carried a diagnosis of hypomelanosis of Ito (300337). Lee et al. (2012) then used a modified single base-extension protocol followed by mass spectrometry analysis to detect somatic mutations at a frequency as low as 3% in genetically heterogeneous samples

Hypomelanosis of Ito is a phenotype well recognized to be associated with chromosomal mosaicism in many cases. None of the patients have peg-shaped teeth or typical retinal vascular changes of incontinentia pigmenti. Happle (1998) concluded that there is convincing evidence that the 'sporadic type of incontinentia pigmenti' (IP1) does not exist A neurocutaneous syndrome characterized by a bizarre, more or less symmetrical leukoderma with depigmented streaks, patches, and whorls, sometimes associated with hyperkeratosis follicularis. Associated disorders include seizures, psychomotor retardation, macrocephaly, and ophthalmological and other abnormalities Hypomelanosis of Ito (HMI) (OMIM 146150), though similar to incontinentia pigmenti (IP) (OMIM 308310), differs by having unilateral or bilateral hypopigmented whorls, streaks and patches. Patients with HMI exhibit a negative pattern of pigmentation compared to IP Abstract. The term hypomelanosis of Ito (HI) (OMIM # 300337) encompasses a heterogeneous group of disorders characterised by hypopigmented whorls and streaks following the lines of Blaschko (Taibjee et al. 2004).Blaschko's lines represent a non-random developmental system of linear and/or whorled streaks first described in 1901 (Blaschko 1901) as a constant pattern of cutaneous markings. Not to be confused with Incontinentia pigmenti. Incontinentia pigmenti achromians (also known as hypomelanosis of Ito ) is a cutaneous condition characterized by various patterns of bilateral or unilateral hypopigmentation following the lines of Blaschko

351 The coexistence of hypomelanosis of Ito and incontinentia pigmenti in the same family, even though disputed by a subsequent author, 352 and the report of several patients with a preceding erythematous or verrucous stage 353. and 354. have led several authorities to postulate a link between these two conditions. 346. and 353 Incontinentia pigmenti (IP) is a genetic ectodermal dysplasia affecting the skin, hair, teeth, microvasculature, and central nervous system. Progressive skin changes occur in four stages, the first of which appear in early infancy or can be present at birth. IP is an X-linked dominant genetic disorder caused by changes (mutations) in the IKBKG. INTRODUCTION. Pigmentary mosaicism of the (hypomelanosis of) Ito type (still known as incontinentia pigmenti achromians; MIM # 300337) is a not uncommon mosaic cutaneous disorder. 1-8 The abnormal skin patterning is characterized by hypopigmentation in the form of whorls, streaks, or patches that may be unilateral or bilateral. 5-8 The hypopigmented streaks and whorls are irregularly.

Updates to this gene will be send to {{ username } OMIM Numbers. 308300; Inheritance. X-linked; Gene/Gene Map. The disease is caused by mutations in the NEMO (NF-Kappa-B Essential Modulator) gene and is referred to as IP2, or classical incontinentia pigmenti. Sporadic incontinentia pigmenti, originally called IP1, maps to Xp11 and is categorized as similar to hypomelanosis of Ito

Hypomelanosis of Ito (OMIM 300337) was ruled out in the present case because of the symmetric and nonsegmental involvement.

The skin phenotype could be designated as hypomelanosis of Ito, but the more specific diagnosis of cutis tricolor of the Blaschko-linear type reflects the association with hypopigmented and hyperpigmented streaks. 22 Indeed, review of photographs of children with hemimegalencephaly or FCD and hypomelanosis of Ito usually reveal hypopigmented. Hypomelanosis of Ito (Disease) Ito syndrome have cells that have the normal chromosomes and some cells with abnormal chromosomes. This is known as chromosomal mosaicism. This condition is not inherited in families. OMIM is maintained by Johns Hopkins University School of Medicine Incontinentia pigmenti (IP), also known as Bloch-Sulzberger syndrome, is a rare X-linked dominantly inherited syndrome manifesting at birth or early childhood. The cardinal feature is the appearance of characteristic progressive skin lesions, first presenting as vesiculobullous lesions and then progressing to whorl-like pigmentary lesions over four stages The term hypomelanosis if Ito should be avoided because it fosters the erroneous belief that there is a nosological entity with this name. In fact, linear hypomelanosis is an umbrella term that includes many different forms of cellular mosaicism that may or may not be discernible at the cytogenetic level [ 142 ]
