Description : Quigley (1993) reviewed adult-onset primary open angle glaucoma, which combines a
particular abnormal appearance of the optic disc (optic nerve head) with a slowly
progressive loss of visual sensitivity. Many patients with glaucoma have intraocular
pressures above the normal range, although this cannot be considered part of the definition
of the disease, since some patients have normal intraocular pressures. Changes in
the optic disc, either inherited or acquired, contribute to the development of the
disorder, which leads to visual loss from increasing nerve fiber layer atrophy. Quigley
et al. (1994) stated that POAG should be reviewed as a multifactorial disorder. -
Genetic Heterogeneity of Primary Open Angle Glaucoma Other forms of primary open angle
glaucoma include GLC1A (137750), caused by mutation in the MYOC gene (601652) on chromosome
1q24.3-q25.2; GLC1B (606689) on chromosome 2cen-q13; GLC1C (601682) on chromosome
3q21-q24; GLC1D (602429) on chromosome 8q23; GLC1F (603383), caused by mutation in
the ASB10 gene on chromosome 7q36; GLC1G (609887), caused by mutation in the WDR36
gene (609669) on chromosome 5q22; GLC1H (611276) on chromosome 2p16-p15; GLC1I (609745)
on chromosome 15q11-q13; GLC1J (608695) on chromosome 9q22; GLC1K (608696) on chromosome
20p12; GLC1L (see 137750) on chromosome 3p22-p21; GLC1M (610535) on chromosome 5q22;
GLC1N (611274) on chromosome 15q22-q24; GLC1O (613100), caused by mutation in the
NTF4 gene (162662) on chromosome 19q13.3; GLC1P (177700), caused by an approximately
300-kb duplication on chromosome 12q24, most likely involving the TBK1 gene (604834).
Nail-patella syndrome (NPS; 161200), which is caused by mutation in the LMX1B gene
(602575) on chromosome 9q34, has open angle glaucoma as a pleiotropic feature. - Other
