Genes affected

FAM111B (HGNC:24200): (FAM111 trypsin like peptidase B) This gene encodes a protein with a trypsin-like cysteine/serine peptidase domain in the C-terminus. Mutations in this gene are associated with an autosomal dominant form of hereditary fibrosing poikiloderma (HFP). Affected individuals display mottled pigmentation, telangiectasia, epidermal atrophy, tendon contractures, and progressive pulmonary fibrosis. Alternative splicing results in multiple transcript variants encoding distinct isoforms. A paralog of this gene which also has a trypsin‐like peptidase domain, FAM111A, is located only 16 kb from this gene on human chromosome 11q12.1. [provided by RefSeq, Apr 2014]

Jun 18, 2021

The c.255G>C (p.L85F) alteration is located in exon 4 (coding exon 2) of the FAM111B gene. This alteration results from a G to C substitution at nucleotide position 255, causing the leucine (L) at amino acid position 85 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
