Mendeliome v1.2559 FBXO22 Zornitza Stark Marked gene: FBXO22 as ready
Mendeliome v1.2559 FBXO22 Zornitza Stark Gene: fbxo22 has been classified as Green List (High Evidence).
Mendeliome v1.2559 FBXO22 Zornitza Stark Classified gene: FBXO22 as Green List (high evidence)
Mendeliome v1.2559 FBXO22 Zornitza Stark Gene: fbxo22 has been classified as Green List (High Evidence).
Mendeliome v1.2558 FBXO22 Sarah Milton gene: FBXO22 was added
gene: FBXO22 was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: FBXO22 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: FBXO22 were set to PMID: 40215970
Phenotypes for gene: FBXO22 were set to Neurodevelopmental disorder, MONDO:0700092, FBXO22-related
Review for gene: FBXO22 was set to GREEN
Added comment: Encodes substrate recognition component of SCF E3 ubiquitin ligase complex. Has role in post translational ubiquitination and degradation of certain substrates e.g. histone demethylases.

14 cases from 12 families published with affected individuals noted to have homozygous frameshift variants (FBXO22:c.159_162del,c.8_36del,c.719_722del - all rare/absent gnomad v4).

Phenotype included prenatal growth restriction/short stature, neurodevelopmental delay, microcephaly, hypotonia, seizures, craniofacial dysmorphisms (high forehead, depressed nasal bridge, hypertelorism), variable additional findings including cardiovascular and gastrointestinal anomalies.

Supportive functional studies - FBXO22 is involved of degradation of KDM4B, KDM4B protein levels in one affected individual were found to be higher than control. Unique genome wide episignature identified for FBXO22 in 3 individuals with the disorder (given loss of this protein results in increased levels of various histone demethylases).
