Genes affected

SERPINH1 (HGNC:1546): (serpin family H member 1) This gene encodes a member of the serpin superfamily of serine proteinase inhibitors. The encoded protein is localized to the endoplasmic reticulum and plays a role in collagen biosynthesis as a collagen-specific molecular chaperone. Autoantibodies to the encoded protein have been found in patients with rheumatoid arthritis. Expression of this gene may be a marker for cancer, and nucleotide polymorphisms in this gene may be associated with preterm birth caused by preterm premature rupture of membranes. Alternatively spliced transcript variants have been observed for this gene, and a pseudogene of this gene is located on the short arm of chromosome 9. [provided by RefSeq, May 2011]

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 183 of the SERPINH1 protein (p.Gly183Ser). This variant is present in population databases (rs758606932, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with SERPINH1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1425510). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SERPINH1 protein function. 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. -
