Genotype and phenotype heterogeneity in perrault syndrome

J Pediatr Adolesc Gynecol. 2013 Feb;26(1):e25-7. doi: 10.1016/j.jpag.2012.10.008.

Abstract

Background: The hallmarks of Perrault syndrome are progressive sensorineural hearing loss and ovarian dysgenesis, but the disorder is both clinically and genetically heterogenous.

Case: 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.

Summary and conclusion: Mutations in HARS2, HSD17B4, and PSMC3IP genes do not explain Perrault syndrome in our patient, indicating that other critical genes remain to be identified.
