Genotype and phenotype heterogeneity in perrault syndrome



Genotype and phenotype heterogeneity in perrault syndrome



Journal of Pediatric and Adolescent Gynecology 26(1): E25-E27



The hallmarks of Perrault syndrome are progressive sensorineural hearing loss and ovarian dysgenesis, but the disorder is both clinically and genetically heterogenous. We report a 15-year-old girl with gonadal dysgenesis, unilateral sensorineural deafness, cataracts in both eyes, and Marfanoid body proportions diagnosed Perrault syndrome. We detected 14 single nucleotide variations including 2 homozygous missense change of c.317G>A (p.Arg106His) and c.1675A>G (p.Ile559Val) in HSD17B4. No significant mutation in HARS2 and PSMC3IP, and gene copy number variant were found as the cause of Perrault syndrome. Mutations in HARS2, HSD17B4, and PSMC3IP genes do not explain Perrault syndrome in our patient, indicating that other critical genes remain to be identified.
