Gonadal (ovarian) dysgenesis with normal chromosomes (46, XX), XX female gonadal dysgenesis (XX-GD) is a rare genetically heterogeneous disorder. In 1951, Perrault reported the association of gonadal dysgenesis and deafness, now referred to as Perrault syndrome. Perrault syndrome is a rare autosomal recessive condition affecting both females and males, only females have gonadal dysgenesis associated with sensorineural deafness which is present in both sexes. We present a case of Sporadic Perrault syndrome in a 35-year-old female with primary amenorrhea, sensorineural deafness, marfanoid features, and normal karyotype. There are very few case reports describing the condition, even lesser reports of association with marfanoid habitus. We report this case for its rarity and add to the spectrum of the disease that remains undetermined.

The mitochondrial ribosome (mitoribosome) synthesizes 13 protein subunits of the oxidative phosphorylation system encoded by the mitochondrial genome. The mitoribosome is composed of 12S rRNA, 16S rRNA, and 82 mitoribosomal proteins encoded by nuclear genes. To date, variants in 12 genes encoding mitoribosomal proteins are associated with rare monogenic disorders and frequently show combined oxidative phosphorylation deficiency.

Combined oxidative phosphorylation deficiency (COXPD) is a rare multisystem disorder which is clinically and genetically heterogeneous. Genome sequencing identified biallelic variants in individuals from five unrelated families with presentations ranging from Perrault syndrome (primary ovarian insufficiency and sensorineural hearing loss) to severe childhood onset of leukodystrophy, learning disability, microcephaly and retinal dystrophy. Complexome profiling of fibroblasts from affected individuals revealed reduced levels of the small and, a more pronounced reduction of, the large mitochondrial ribosomal subunits.
