Chirag Patel gene: RFC4 was added gene: RFC4 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: RFC4 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: RFC4 were set to PMID: 39106866 Phenotypes for gene: RFC4 were set to RFC4-related multisystem disorder Review for gene: RFC4 was set to GREEN gene: RFC4 was marked as current diagnostic Added comment: 9 affected individuals (aged birth to 47yrs) from 8 unrelated families with a multisystem disorder. Clinical features included: muscle weakness/myopathy (9/9), motor incoordination/gait disturbance (8/8), delayed gross motor development (6/9), dysarthria (5/5), peripheral neuropathy (3/3 adults), bilateral sensorineural hearing impairment (6/9), decreased body weight (8/9), short stature (5/9), microcephaly (4/9), respiratory issues/insufficiency (6/9), cerebellar atrophy (4/9), pituitary hypoplasia (3/9). WES or WGS identified biallelic loss-of-function variants in RFC4 (3 frameshift, 2 splice site, 1 single AA duplication, 2 single AA deletions, 2 missense), and almost all are likely to disrupt the C-terminal domain indispensable for Replication factor C (RFC) complex formation. All variants segregated with the disease. The RFC complex (with 5 subunits) is central to process of regulation of DNA replication, and it loads proliferating cell nuclear antigen onto DNA to facilitate the recruitment of replication and repair proteins and enhance DNA polymerase processivity. RFC1 is associated with CANVAS but the contributions of RFC2-5 subunits on human Mendelian disorders is unknown. Analysis of a previously determined cryo-EM structure of RFC bound to proliferating cell nuclear antigen suggested that the variants disrupt interactions within RFC4 and/or destabilize the RFC complex. Cellular studies using RFC4-deficient HeLa cells and primary fibroblasts demonstrated decreased RFC4 protein, compromised stability of the other RFC complex subunits, and perturbed RFC complex formation. Additionally, functional studies of the RFC4 variants affirmed diminished RFC complex formation, and cell cycle studies suggested perturbation of DNA replication and cell cycle progression.
