Identification of a functionally significant tri-allelic genotype in the Tyrosinase gene (TYR) causing hypomorphic oculocutaneous albinism (OCA1B)

Scientific Reports, 2017
Oculocutaneous albinism (OCA) and ocular albinism (OA) are inherited disorders of melanin biosynthesis, resulting in loss of pigment and severe visual deficits. OCA encompasses a range of subtypes with overlapping, often hypomorphic phenotypes.

Impact of obesity with impaired glucose tolerance on retinal degeneration in a rat model of metabolic syndrome. [PDF]

, 2017
PurposeMetabolic syndrome (MetS) is associated with several degenerative diseases, including retinal degeneration. Previously, we reported on progressive retinal degeneration in a spontaneous obese rat (WNIN/Ob) model.

Tyrosinase Gene Mutations Causing Oculocutaneous Albinisms.

Journal of Investigative Dermatology, 1993
Since the first report of a mutation in the tyrosinase gene that causes tyrosinase-negative oculocutaneous albinism (OCA), more than 25 alleles with a different mutation in patients with three types of OCA, i.e., tyrosinase-negative OCA (type IA), yellow-mutant OCA (type IB), and temperature sensitive OCA (type ITS), have been found in several ...

Oculocutaneous albinism type 4: Novel compound heterozygous mutations in the SLC45A2 gene in a Chinese case

Molecular Genetics & Genomic Medicine
Background Oculocutaneous albinism type 4 (OCA4) is a rare autosomal recessive disorder characterized by a reduction of pigmentation in skin, hair, and eyes, and OCA4 is mainly seen in the SLC45A2 gene variants.

A Case of Hermansky–Pudlak Syndrome

Journal of Association of Pulmonologist of Tamil Nadu
Hermansky–Pudlak syndrome (HPS) is a rare autosomal recessive disorder characterized by a triad of oculocutaneous albinism, bleeding diathesis, and lysosomal storage defects. One of the most severe complications of HPS is interstitial lung disease. There

Photoprotective behaviours amongst persons with albinism in Uyo, Nigeria

JEADV Clinical Practice
Background Strict photoprotection is crucial for persons living with albinism (PWAs), especially in Nigeria where the level of solar ultraviolet radiation is particularly high, which further increases the susceptibility of this population to develop ...
