Mendeliome v1.711 OXR1 Achchuthan Shanmugasundram changed review comment from: Comment on gene rating: This gene should be rated AMBER as there is one case and supportive functional data to associate OXR1 with hearing loss.

A four years old girl was identified with a novel homozygous missense variant (c.233A > G, p.Lys78Arg) in OXR1 gene and was reported with sensorineural hearing loss.

Functional studies in zebrafish model showed that the ortholog orx1b gene is expressed in the statoacoustic ganglion (SAG, a sensory ganglion of ear) and posterior lateral line ganglion (pLL). In addition, knockdown of oxr1b resulted in a significant developmental defect of SAG and pLL and this phenotype was rescued by co-injection of wild-type human OXR1 mRNAs, but not mutant OXR1 (c.233A > G) mRNAs.; to: Comment on gene rating: This gene should be rated AMBER as there is one case and supportive functional data to associate OXR1 with hearing loss.

This gene has not yet been associated with hearing loss either in OMIM or in Gene2Phenotype.
Mendeliome v1.711 OXR1 Achchuthan Shanmugasundram reviewed gene: OXR1: Rating: AMBER; Mode of pathogenicity: None; Publications: 36130215; Phenotypes: sensorineural hearing loss disorder, MONDO:0020678; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal

Mendeliome v0.10025 FOXR1 Zornitza Stark Classified gene: FOXR1 as Amber List (moderate evidence)
Mendeliome v0.10025 FOXR1 Zornitza Stark Gene: foxr1 has been classified as Amber List (Moderate Evidence).
Mendeliome v0.10017 FOXR1 Paul De Fazio gene: FOXR1 was added
gene: FOXR1 was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: FOXR1 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Publications for gene: FOXR1 were set to 34723967
Phenotypes for gene: FOXR1 were set to Postnatal microcephaly, progressive brain atrophy and global developmental delay
Review for gene: FOXR1 was set to AMBER
gene: FOXR1 was marked as current diagnostic
Added comment: 1 patient described with a de novo missense variant. Phenotypes include: postnatal microcephaly, progressive brain atrophy, skeletal abnormalities, brain abnormalities, ophthalmic abnormalities, neuromuscular abnornmalities, and dysmorphic features.

In vitro functional evidence is supportive of pathogenicity (variant causes protein instability and abnormal nuclear aggregation).

A mouse knockout has comparable phenotypes, and a severe survival deficit.

Rated amber (1 patient, functional evidence, mouse model).
