Genes affected

FAM111A (HGNC:24725): (FAM111 trypsin like peptidase A) 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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.05294481).

BS1

Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000274 (40/1461416) while in subpopulation SAS AF= 0.000244 (21/86240). AF 95% confidence interval is 0.000163. There are 0 homozygotes in gnomad4_exome. There are 26 alleles in male gnomad4_exome subpopulation. Median coverage is 29. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAdExome at 9 AD gene.

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 9 of the FAM111A protein (p.Arg9Trp). This variant is present in population databases (rs758432983, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with FAM111A-related conditions. ClinVar contains an entry for this variant (Variation ID: 1428044). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
