Turner's syndrome in dermatology

Area of Science:

• Genetics
• Endocrinology
• Dermatology

Background:

• Turner's syndrome (TS) is a common genetic disorder in females, characterized by short stature, impaired sexual development, and infertility.
• While often associated with monosomy X, TS exhibits genetic heterogeneity, including mosaicism, which influences disease presentation and survival.
• Cutaneous manifestations are key indicators for early TS detection and can predict systemic complications.

Purpose of the Study:

• To provide new insights into the genetics and pathogenesis of Turner's syndrome.
• To summarize the major systemic effects of TS across various organs.
• To review the skin manifestations of TS and their clinical implications for diagnosis and management.

Main Methods:

• Literature review of recent studies on Turner's syndrome genetics and pathogenesis.
• Synthesis of data on systemic effects in TS patients.
• Analysis of dermatological findings and their association with TS.

Main Results:

• Genetic factors, including the short stature homeobox gene, are implicated in TS.
• TS affects multiple organ systems, with skin stigmata like lymphedema being important diagnostic clues.
• While benign nevi may increase, TS patients show a decreased melanoma rate, suggesting a protective factor; autoimmune diseases like alopecia areata and vitiligo are common.

Conclusions:

• Understanding the genetic heterogeneity and pathogenesis of TS is crucial.
• Early detection through cutaneous signs can lead to timely management of systemic and developmental issues.
• Further research into protective factors against melanoma and the prevalence of autoimmune conditions in TS is warranted.
