Modes of inheritance:
Autosomal dominant inheritance
MedGen UID:

•Concept ID:
C0443147
•
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Definition

Type II granular corneal dystrophy (GCDII) is a rare form of stromal corneal dystrophy (see this term) characterized by irregular-shaped well-demarcated granular deposits in the superficial central corneal stroma, and progressive visual impairment. [from ORDO]

Clinical features

From HPO
Lattice corneal dystrophy
MedGen UID:
56355
•Concept ID:
C0155127
•
Disease or Syndrome
The presence of fine, branching linear opacities in Bowman's layer in the central area that may spread to the periphery in the clinical course. The deep corneal stroma may be involved but the process does not reach Descemet's membrane. Recurrent corneal erosion may occur. Histologic examination reveals amyloid deposits in the collagen fibers of the cornea.

Reduced visual acuity
MedGen UID:
65889
•Concept ID:
C0234632
•
Finding
Diminished clarity of vision.

Visual impairment
MedGen UID:
777085
•Concept ID:
C3665347
•
Finding
Visual impairment (or vision impairment) is vision loss (of a person) to such a degree as to qualify as an additional support need through a significant limitation of visual capability resulting from either disease, trauma, or congenital or degenerative conditions that cannot be corrected by conventional means, such as refractive correction, medication, or surgery.
