Isolation and chromosomal localization of a cornea-specific human keratin 12 gene and detection of four mutations in Meesmann corneal epithelial dystrophy. Trans Am Ophthalmol Soc.

Affected patients may have ocular involvement, oral involvement, or both. Oral manifestations of the disease include white, spongy plaques of the buccal mucosa, tongue, or lips [13]. Author manuscript; available in PMC Mar 1.

Yanoff hdreditary the condition in mother and daughter. The corneal plaques in these patients were larger and led to severe neovascularization dyskeratoosis, as well as total opacification in one eye. Sign in to customize your interests Sign in to your personal account. Hereditary benign intraepithelial dyskeratosis is a clinical diagnosis. Even in the Caucasian French family in which the NLRP1 missense mutation was identified, questions remain about the pathogenicity of the identified variant, which was identified in just two affected individuals and absent in five unaffected individuals that were screened.

NLRP1 gene sequencing failed to reveal a presumed pathogenic variant. The absence of a NLRP1 coding region mutation and even a predicted gene in the region of 4q35 duplicated in both the Caucasian American individual we report and in two Haliwa-Saponi Native American families is evidence of a distinct genetic locus for HBID.

As a second test for locus heterogeneity in HBID, we performed both copy number variant analysis and whole exome sequencing in a previously unreported Caucasian American individual with histopathologically-confirmed HBID.

Of note, a gene was not localized in this region. Copy number variant CNV analysis revealed a de novo 4q35 duplication that overlapped the duplication previously associated with HBID, although no genes were identified in the common interval.

Epub Jan 16 doi: This was the only report of the condition in persons apparently unrelated to the North Carolinian triracial isolate, the ‘Haliwa Indians,’ studied by Witkop and Gorlin The corneal plaques may become visually significant with extension into the central visual axis, disruption the normal ocular surface, or induction of astigmatism.

Clinicopathological features of a suspected case of hereditary benign intraepithelial dyskeratosis with bilateral corneas involved: National Center for Biotechnology InformationU. Examination of her mother revealed dilated vessels and a superficial gelatinous plaque on the bulbar conjunctiva; a maternal uncle and the maternal grandmother also had dilated vessels and superficial gelatinous plaque on the bulbar conjunctiva, as well as white papules on the buccal mucosa.

The hallmark dyskeratotic cells in hereditary benign intraepithelial dyskeratosis have a dense cytoplasm and pyknotic nuclei.

The location of previously reported duplications and incidence of each in control populations Database of Genomic Variants are depicted underneath the schematic.

Topical management alone has not shown to reduce plaque size in the majority of cases [15] [14]. The location and names of genes in the duplicated regions are shown. Ocular and oral plaques are distinctively characterized by acanthosis, dyskeratosis, and parakeratosis within the stratified squamous epithelium.

Bilateral, marked, red eyes is the most common symptom due to bulbar conjunctival hyperemia. The eye lesions were invariably associated with a comparable epithelial heredirary of the oral mucosa. Show all Hide all. Hereditary benign intraepithelial dyskeratosis.
