Myopia 23, autosomal recessive(MYP23)

MedGen UID:
815812
•Concept ID:
C3809482
•
Disease or Syndrome
Synonym: MYP23
 
Gene (location): LRPAP1 (4p16.3)
 
Monarch Initiative: MONDO:0014183
OMIM®: 615431

Definition

Myopia, or nearsightedness, is a refractive error of the eye. Light rays from a distant object are focused in front of the retina and those from a near object are focused in the retina; therefore distant objects are blurry and near objects are clear (summary by Kaiser et al., 2004). For a discussion of genetic heterogeneity of myopia, see 160700. [from OMIM]

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.
