Towards the Albino Mutant Gene in Borkh.

Plants (Basel)

December 2024

Changli Institute of Pomology, Hebei Academy of Agricultural and Forestry Science, Qinhuangdao 066600, China.

Albino mutation is among the most common phenomena that often causes a water imbalance and disturbs physiological functions in higher species of trees. Albinism frequently occurs in hybridized apples, but almost all seedlings die shortly after germination. In this study, a spontaneous albino mutant on Fuji apple trees was obtained.

Article Synopsis
  • Inherited retinal dystrophies (IRDs) are a significant cause of blindness or severe visual impairment in children, with varying symptoms and genetic associations.
  • The study analyzed data from 309 pediatric patients to determine the clinical and genetic profiles of IRDs, finding distinct patterns in preschoolers versus school-aged children.
  • Preschoolers exhibited symptoms like nystagmus and established genetic variants linked to isolated and syndromic forms of IRDs, while school-aged children largely showed declining visual acuity and a higher prevalence of cone-dominated diseases.

Autosomal recessive conditions are often associated with homozygous mutations showing common ancestral origins and are frequently linked to consanguinity. However, an increasing number of compound heterozygotes are found in diverse, admixed populations. Oculocutaneous albinism (OCA) is a recessive condition caused mainly by mutations in the TYR and OCA2 genes involved in skin pigmentation.

Genotypic spectrum of albinism in Mali.

Pigment Cell Melanoma Res

November 2024

Laboratoire Maladies Rares, Génétique et Métabolisme, Bordeaux University INSERM U1211, Bordeaux, France.

Albinism is a phenotypically and genetically heterogeneous condition characterized by a variable degree of hypopigmentation and by ocular features leading to reduced visual acuity. Whereas numerous genotypic studies have been conducted throughout the world, very little is known about the genotypic spectrum of albinism in Africa and especially in sub-Saharan Western Africa. Here we report the analysis of all known albinism genes in a series a 23 patients originating from Mali.
