  • Small Widely Spaced Teeth

    The brother exhibited minimal symptoms, having mild bilateral syndactyly between fingers 1, 2, 3, and 4 and small, widely spaced teeth, but an unremarkable ophthalmologic and hair examination. REFERENCES Albergaria, A., Ribeiro, A. [ncbi.nlm.nih.gov]

  • Alopecia

    The hair phenotype does not improve significantly with age, even though diffuse alopecia in infancy can evolve towards short and sparse hair in puberty. Etiology HJMD is caused by mutations in the CDH3 gene (16q22.1), encoding P-cadherin. [orpha.net]

    Entry H00785 Disease Name Congenital hypotrichosis with juvenile macular dystrophy Description Hypotrichosis with juvenile macular dystrophy is a rare autosomal recessive disorder characterized by sparse scalp hair from birth and resulting hair loss associated [genome.jp]

    HJMD has been described as macular degeneration and short sparse scalp hair from birth with hair loss during the first months of life [ 5 ]. The retinal phenotype is nowadays being re-evaluated. [bmcmedgenet.biomedcentral.com]

    In addition, macular hyperpigmentation was present as detected by photographic fluorescein angiogram and color fundus photography. [karger.com]

  • Retinal Pigmentation

    We put forward arguments for locating the retinal alteration at the level of the retinal pigment epithelium and suggest that the hair disorder could be a Marie-Unna type hypotrichosis. [ncbi.nlm.nih.gov]

    Moreover, P-cadherin is expressed in the retinal pigment epithelium. Diagnostic methods Diagnosis is based on the combined occurrence of hypotrichosis with characteristic degenerative changes and pigmentary abnormalities of the macula on fundoscopy. [orpha.net]

    Optical coherence tomography (OCT) demonstrated variable degrees of atrophy of the outer retina, retinal pigment epithelium, and choroid, with outer retinal tubulations frequently observed. [ndcn.ox.ac.uk]

  • Central Scotoma

  • Visual Acuity Decreased

    A decade later, during the first to third decades of life, visual acuity decreases because of progressive macular degeneration, leading in many cases to blindness between the second and fourth decades of life. [orpha.net]

    Visual acuity decreases slowly in spite of significant deterioration of cone- and rod-mediated retinal function. [disorders.eyes.arizona.edu]

In breast cancer, P-cadherin is frequently overexpressed in high-grade tumours and is a well-established indicator of aggressive tumour behaviour and poor patient prognosis. [journals.plos.org]

Moreover, the expression of P-cadherin and CEBPB were highly associated in human breast carcinomas and linked with a worse prognosis in breast cancer patients. [ncbi.nlm.nih.gov]

Etiology HJMD is caused by mutations in the CDH3 gene (16q22.1), encoding P-cadherin. P-cadherin is part of adherens junctions in various epithelia including the hair follicular epithelium. [orpha.net]
