Genes affected

CARMIL2 (HGNC:27089): (capping protein regulator and myosin 1 linker 2) This gene encodes a member of the CARMIL (capping protein, Arp2/3, myosin-I linker) family of proteins. The encoded protein interacts with and negatively regulates the heterodimeric capping protein and promotes cell migration. Reduced expression of this gene has been observed in human psoriasis patients. Mutations in this gene cause a human immunodeficiency syndrome characterized by smooth muscle tumors and impaired T-cell function. [provided by RefSeq, May 2017]

The p.Gln891Pro variant in RLTPR has not been previously reported, but was ident ified in 7/66280 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). Computational prediction tools and conservatio n analyses suggest that the variant may not impact the protein, though this info rmation is not predictive enough to rule out pathogenicity. In summary, the clin ical significance of the p.Gln891Pro variant is uncertain. -

This sequence change replaces glutamine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 891 of the CARMIL2 protein (p.Gln891Pro). This variant is present in population databases (rs769736838, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with CARMIL2-related conditions. ClinVar contains an entry for this variant (Variation ID: 229203). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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. -
