TYRTyrosinaseDisease-causing germline mutation(s) inTolerante
FUNÇÃO

This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds. Catalyzes the initial and rate limiting step in the cascade of reactions leading to melanin production from tyrosine (By similarity). In addition to hydroxylating tyrosine to DOPA (3,4-dihydroxyphenylalanine), also catalyzes the oxidation of DOPA to DOPA-quinone, and possibly the oxidation of DHI (5,6-dihydroxyindole) to indole-5,6 quinone (PubMed:28661582)

Albinism, oculocutaneous, 1A

An autosomal recessive disorder in which the biosynthesis of melanin pigment is absent in skin, hair, and eyes. It is characterized by complete lack of tyrosinase activity due to production of an inactive enzyme. Patients present with a life-long absence of melanin pigment after birth, and manifest increased sensitivity to ultraviolet radiation with predisposition to skin cancer. Visual anomalies include decreased acuity, nystagmus, strabismus and photophobia.

Receptor for tyrosine, L-DOPA and dopamine. After binding to L-DOPA, stimulates Ca(2+) influx into the cytoplasm, increases secretion of the neurotrophic factor SERPINF1 and relocalizes beta arrestin at the plasma membrane; this ligand-dependent signaling occurs through a G(q)-mediated pathway in melanocytic cells. Its activity is mediated by G proteins which activate the phosphoinositide signaling pathway. Also plays a role as an intracellular G protein-coupled receptor involved in melanosome b

Hermansky-Pudlak syndrome 10

A form of Hermansky-Pudlak syndrome, a genetically heterogeneous autosomal recessive disorder characterized by oculocutaneous albinism, bleeding due to platelet storage pool deficiency, and lysosomal storage defects. This syndrome results from defects of diverse cytoplasmic organelles including melanosomes, platelet dense granules and lysosomes. Ceroid storage in the lungs is associated with pulmonary fibrosis, a common cause of premature death in individuals with HPS. HPS10 patients manifest albinism, neutropenia, immunodeficiency, neurodevelopmental delay, generalized seizures, and impaired hearing.

First Report of Oculocutaneous Albinism Type I Among Baka Pygmies From Cameroon.

Pigment cell & melanoma research2026 Jan

Oculocutaneous albinism type 1 (OCA1) caused by pathogenic variants of the TYR gene is an autosomal recessive disorder of pigmentation characterized by reduced biosynthesis of melanin pigment in skin, hair, and eyes. We had the opportunity to examine five East Cameroon Baka rainforest hunter-gatherers (historically called "Pygmies") with albinism and belonging to three different families. Screening of known albinism genes revealed a homozygous missense variant in the TYR gene, NM_000372.5: c.1109T>C; p.Met370Thr. In addition, one patient was also hemizygous for a variant in GPR143, the gene involved in ocular albinism (OA1). Another patient was also heterozygous for the common African and Afro-American 2.7-kb deletion in the OCA2 gene indicating admixture of one parent with neighboring Nzimé Bantu-speaking farmers. This is the first report of the occurrence of OCA1 in African rainforest hunter-gatherers.

Disruption of the l-DOPA Receptor Gpr143/OA1-Gene in Mice Creates a Unique Mixed Psychosis-Like Phenotype.

Neuropsychopharmacology reports2026 Mar

GPR143, originally identified as the gene product of ocular albinism 1 (OA1), a G protein-coupled receptor (GPCR), can function as a receptor for l-3,4-dihydroxyphenylalanine (DOPA), a precursor of dopamine (DA). To examine the physiological and pathophysiological roles of GPR143, we analyzed the behavior of Gpr143 gene-deficient (Gpr143-/y) mice. We performed comprehensive behavioral analyses including the prepulse inhibition test, sucrose preference test, light-dark exploration test, etc. and microarray analysis. Gpr143-/y mice displayed a mixed psychosis-like phenotype: impaired prepulse inhibition (a characteristic of schizophrenia) combined with reward system aberrations, depression, and heightened aggression (characteristic of mood disorders). By microarray analysis, we identified 17 downregulated and 20 upregulated genes in the forebrain of Gpr143-/y mice, genes putatively involved in serotonergic and/or dopaminergic transmission. These findings suggest that GPR143 plays a role in mesolimbic and mesocortical functions underlying sensory gating, reward, social hierarchy, cognition, and emotional regulation. These data further suggest both a new animal model and a unique therapeutic focus for a heretofore difficult to study and treat mixed psychosis-like condition.

Updated Analysis of Albinism in Japan: 290 Families With Novel Pathological Variants.

Pigment cell & melanoma research2025 Nov

We present an updated analysis of albinism in Japan, encompassing both oculocutaneous albinism (OCA) and ocular albinism (OA), based on 290 families, which expands our previous study by 100 additional families. The overall frequency distribution of major subtypes remained consistent with our previous findings: OCA4 remains the most prevalent subtype (67 patients, 23.1%), followed by OCA1 (57 patients, 19.7%), Hermansky-Pudlak syndrome (HPS) 1 (35 patients, 12.1%), and OCA2 (30 patients, 10.3%). Notably, our expanded analysis identified patients with rare subtypes, including OCA3, OCA6, HPS2, HPS3, HPS5, and HPS6, as well as OA, further demonstrating the genetic diversity of albinism in the Japanese population. Through comprehensive genetic screening of the additional 100 families, we identified 17 patients harboring previously unreported pathological variants across multiple albinism subtypes. These findings expand the variant spectrum of albinism in Japan, provide valuable insights for genetic counseling, and underscore the critical importance of comprehensive clinical evaluation and long-term multidisciplinary follow-up for patients with albinism, particularly those with HPS subtypes.

Pigmentation Pattern of Iris and Fundus in 75 Chinese Families With GPR143-Associated Ocular Albinism.

Investigative ophthalmology & visual science2025 Sep 02

Ocular albinism is an X-linked recessive genetic disorder that exhibits highly heterogeneous phenotypes involving significant visual deficits and pigmental changes in the eye due to GPR143 variants. The aim of this study is to describe the phenotypic spectra of patients with ocular albinism based on the identification of GRP143 variants in a large Chinese cohort. GPR143 variants were selected from an in-house data set. Potential pathogenic variants were evaluated using multiple bioinformatic analyses and validated by Sanger sequencing. Clinical data of individuals with likely pathogenic variants in GPR143 were thoroughly analyzed. Forty-six hemizygous variants (18 missense, 8 stop-gain, 8 splicing, 5 frameshift, 6 deletion, and 1 in-frame insertion), including 31 novel ones, were detected in 75 probands with ocular albinism. Three distinct patterns of iris pigmentation and three grades of fundus pigmentation were classified according to available data of the 75 families. Pattern II of iris, characterized by hyperpigmentation in the peripupillary area, was the most prevalent, with involvement of 41.2% of patients. Approximately 52.1% of patients exhibited atypical pigment changes in both the iris and the fundus. Patients with grade 3 fundus, characterized by pronounced depigmentation in the macular region, exhibited significantly poorer best-corrected visual acuity compared to those with other grades (P = 0.0031). Follow-up examinations indicated that fundus pigment deposition increased with age during early childhood. This study expands the variant spectrum of GPR143 and clarifies phenotypic features of ocular albinism, facilitating diagnosis. Hyperpigmentation in the peripupillary area suggests a complex role of GPR143 in melanosome production.
