Oculocutaneous albinism with iridofundal coloboma [PDF]

open access: yesBMJ Case Reports, 2018
A 20-year-old woman presented to the retina clinic with complaints of diminution of vision, photophobia and involuntary movement of both eyes since birth. The patient had light-coloured skin complexion along with golden hair. Best corrected visual acuity was 1/60 and 4/60 in the right and left eyes, respectively.

Oculocutaneous albinism in a patient with 17p13.2-pter duplication - a review on the molecular syndromology of 17p13 duplication

open access: yesBiomedical Papers, 2015
Background: Chromosomal duplications involving 17p13.3 have recently been defined as a new distinctive syndrome with several diagnosed patients. Some variation is known to occur in the breakpoints of the duplicated region and, consequently, in the ...

Human pigmentation genes under environmental selection [PDF]

open access: yes, 2012
Genome-wide association studies and comparative genomics have established major loci and specific polymorphisms affecting human skin, hair and eye color. Environmental changes have had an impact on selected pigmentation genes as populations have expanded

Rare Germline Variants in CDKN2A‐Negative Children and Adolescents With Cutaneous Melanoma

open access: yesPigment Cell &Melanoma Research, Volume 39, Issue 2, March 2026.
Individuals with childhood and adolescent melanoma carry inherited mutations in shelterin complex genes, pigmentation genes and MBD4, but have fewer MC1R R‐alleles than adults with melanoma. Created with BioRender.com. ABSTRACT Cutaneous melanoma is a complex disease influenced by both environmental and genetic factors. Inherited susceptibility plays a

A nonsense mutation in the tyrosinase gene causes albinism in water buffalo

open access: yesBMC Genetics, 2012
Background Oculocutaneous albinism (OCA) is an autosomal recessive hereditary pigmentation disorder affecting humans and several other animal species. Oculocutaneous albinism was studied in a herd of Murrah buffalo to determine the clinical presentation ...

Genetic Pigmentary Disorders: From Molecular Mechanisms to Clinical Manifestations

open access: yesThe Journal of Dermatology, Volume 53, Issue 2, Page 169-179, February 2026.
ABSTRACT Genetic pigmentary disorders represent a diverse group of genetic conditions characterized by alterations in melanin production and transport and melanocyte development, resulting from single‐gene pathological variants. These disorders encompass both hypopigmentary and hyperpigmentary phenotypes, affecting not only skin pigmentation but also ...

Children with albinism in African regions: their rights to ‘being’ and ‘doing’

open access: yesBMC International Health and Human Rights, 2018
Background Albinism is an inherited condition with a relatively high prevalence in populations throughout sub-Saharan Africa. People with oculocutaneous albinism have little or no pigment in their hair, skin and eyes; thus they are visually impaired and ...

Pigments, Chromatophore Structure, and Gene Expression Underlying Colour Polytypy of a Panamanian Poison Frog

open access: yesMolecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Colour polytypism represents an example of phenotypic diversification shaped by genetic divergence and ecological pressures. Poison frogs of the genus Oophaga (Dendrobatidae) are highly polytypic in coloration, making them an ideal system for investigating the genetic and physiological basis of colour variation.

Membrane-Associated Transporter Protein (MATP) Regulates Melanosomal pH and Influences Tyrosinase Activity [PDF]

open access: yes
The SLC45A2 gene encodes a Membrane-Associated Transporter Protein (MATP). Mutations of this gene cause oculocutaneous albinism type 4 (OCA4). However, the molecular mechanism of its action in melanogenesis has not been elucidated.
