Presentation
RESULTS: All 10 patients (7 male and 3 female) presented with central visual disturbance in childhood and had lifelong sparse scalp hair with normal facial hair. [ncbi.nlm.nih.gov]
Clinical description HJMD patients present with short and sparse scalp hair since birth or first months of life, with no subsequent growth during life. [orpha.net]
We present a new case of Hypotrichosis with Juvenile Macular Dystrophy. [bmcmedgenet.biomedcentral.com]
Eyes
- 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]

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]

- Sparse Scalp Hair from Birth
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]

Prognosis
Prognosis The most severe complication of HJMD is progressive macular degeneration leading to blindness between the second and fourth decades of life. [orpha.net]

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]
[…] the CDH3 gene encoding P-cadherin underlying hypotrichosis with juvenile macular dystrophy in consanguineous families. findings suggest that E-cadherin and P-cadherin, but not N-cadherin staining, might be useful in diagnosing CIN and for predicting prognosis [ncbi.nlm.nih.gov]
Etiology
These results establish the molecular etiology of HJMD and implicate for the first time a cadherin molecule in the pathogenesis of a human hair and retinal disorder. [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]
