From NCBI Gene:
The protein encoded by this gene is cell-cycle regulated, and has nuclear localization. The C-terminal half of the protein shares homology with trypsin-like peptidases and it contains a PCNA-interacting peptide (PIP) box, that is necessary for its co-localization with proliferating cell nuclear antigen (PCNA). Reduced expression of this gene resulted in DNA replication defects, consistent with the demonstrated role for this gene in Simian Virus 40 (SV40) viral replication. Mutations in this gene have been associated with Kenny-Caffey syndrome (KCS) type 2 and the more severe osteocraniostenosis (OCS, also known as Gracile Bone Dysplasia), both characterized by short stature, hypoparathyroidism, bone development abnormalities, and hypocalcemia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015]
Chromatin-associated protein required for PCNA loading on replication sites. Promotes S-phase entry and DNA synthesis (PubMed:24561620). May directly function at replication forks, explaining why Simian virus 40 (SV40) interacts with FAM111A to overcome host range restriction (PubMed:23093934).

- Gracile bone dysplasia
- Kenny-Caffey syndrome type 2
Gracile bone dysplasia (GCLEB): A perinatally lethal condition characterized by narrowing of the medullary cavity of the long bones and of the skull, gracile bones with thin diaphyses, premature closure of basal cranial sutures, and microphthalmia. Most affected individuals who survive beyond the perinatal period develop hypocalcemia with low parathyroid hormone levels. [MIM:602361]
Kenny-Caffey syndrome 2 (KCS2): A disorder characterized by impaired skeletal development with small and dense bones, short stature, and primary hypoparathyroidism with hypocalcemia. Clinical features include cortical thickening and medullary stenosis of the tubular bones, delayed closure of fontanels, defective dentition, small eyes with hypermetropia, and frontal bossing with a triangular face.
