Genetic Pigmentary Disorders: From Molecular Mechanisms to Clinical Manifestations

The 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 ...

Use of next-generation sequencing and candidate gene analysis to identify underlying defects in patients with inherited platelet function disorders [PDF]

, 2015
Background: Inherited platelet function disorders (PFDs) are heterogeneous, and identification of the underlying genetic defects is difficult when based solely on phenotypic and clinical features of the patient. Objective: To analyze 329 genes regulating

Tissue‐Resident Myeloid and Histiocytic Cells in Health and Disease: Novel Emerging Concepts

American Journal of Hematology, Volume 100, Issue 12, Page 2305-2319, December 2025.
ABSTRACT Although all myeloid cells are considered to derive from hematopoietic stem cells, the cells in each myeloid lineage are heterogeneous populations, and their distribution and functions vary, depending on underlying physiologic and pathologic processes, age, sex, and genetic and epigenetic signatures.

Functional and Morphological Plasticity of the Endolysosomal System: Pigment Organelles at the Crossroads of Physiology and Pathology

Biology of the Cell, Volume 117, Issue 10, October 2025.
The morphodynamical plasticity of the endolysosomal system supports the formation and function of specialized intracellular compartments, as exemplified by the pigment organelles in skin cells. In epidermal melanocytes and keratinocytes, membrane trafficking and remodeling coordinate tissue pigmentation and protect the genome from photodamage ...

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

Generation of Hermansky–Pudlak Syndrome Type 1 (HPS1) induced pluripotent stem cells (iPSCs)

Stem Cell Research, 2016
Hermansky–Pudlak syndrome (HPS) is a rare autosomal recessive disorder characterized by deficiencies in lysosome-related organelles such as melanosomes and platelet-dense granules. The disorder is classified into nine different subtypes (HPS1–HPS9) based
