Genes affected

SRP72 (HGNC:11303): (signal recognition particle 72) This gene encodes the 72 kDa subunit of the signal recognition particle (SRP), a ribonucleoprotein complex that mediates the targeting of secretory proteins to the endoplasmic reticulum (ER). The SRP complex consists of a 7S RNA and 6 protein subunits: SRP9, SRP14, SRP19, SRP54, SRP68, and SRP72, that are bound to the 7S RNA as monomers or heterodimers. SRP has at least 3 distinct functions that can be associated with the protein subunits: signal recognition, translational arrest, and ER membrane targeting by interaction with the docking protein. Mutations in this gene are associated with familial bone marrow failure. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 207 of the SRP72 protein (p.Arg207His). This variant is present in population databases (rs387907189, gnomAD 0.007%). This missense change has been observed in individual(s) with clinical features of SRP72-related conditions (PMID: 22541560). ClinVar contains an entry for this variant (Variation ID: 31660). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on SRP72 protein function. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on SRP72 function (PMID: 22541560). 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. -
