Comprehensive Insights into Perrault Syndrome: Genetic Diversity and Clinical Implications

Area of Science:

• Genetics
• Molecular Biology
• Reproductive Biology

Background:

• Perrault syndrome is an autosomal recessive disorder.
• It presents with sensorineural hearing loss and primary ovarian insufficiency.
• The condition exhibits significant genetic and clinical heterogeneity.

Purpose of the Study:

• To review and synthesize current data on the genetic architecture of Perrault syndrome.
• To identify key genes associated with the disorder.
• To correlate genetic mutations with observed clinical phenotypes.

Main Methods:

• Comprehensive literature review of studies on Perrault syndrome.
• Analysis of mutations in fifteen principal genes involved in mitochondrial or peroxisomal function.
• Correlation of genotype with phenotype data.

Main Results:

• Mutations in fifteen genes (e.g., HSD17B4, HARS2, CLPP, LARS2) are identified as principal causes.
• These genes are critical for mitochondrial function or peroxisomal processes.
• Homozygous variants (56.1%) and compound heterozygous variants (43.9%) were observed.

Conclusions:

• Genetic heterogeneity contributes to the diverse clinical presentations of Perrault syndrome.
• Advanced genetic screening is essential for accurate diagnosis.
• Gene-specific therapies hold potential for managing clinical manifestations.
