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]

SIB Swiss Institute of Bioinformatics

Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: curation

This variant is interpreted as a Likely pathogenic for Immunodeficiency 58, autosomal recessive. The following ACMG Tag(s) were applied: PM2 : Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PP3 : Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PP1 : Cosegregation with disease in multiple affected family members in a gene definitively known to cause the disease (PMID:27896283). PM1 : Located in a mutational hot spot and/or critical and well-established functional domain (e.g., active site of an enzyme) without benign variation. -

Collection Method: clinical testing

This sequence change replaces leucine, which is neutral and non-polar, with histidine, which is basic and polar, at codon 639 of the CARMIL2 protein (p.Leu639His). This variant is present in population databases (rs775061512, gnomAD 0.01%). This missense change has been observed in individual(s) with clinical features of primary immunodeficiency (PMID: 27896283). ClinVar contains an entry for this variant (Variation ID: 565281). 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 expected to disrupt CARMIL2 protein function with a positive predictive value of 80%. 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. -
