Genes affected
CORO1A (HGNC:2252): (coronin 1A) This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD), which may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. Alternative splicing results in multiple transcript variants. A related pseudogene has been defined on chromosome 16. [provided by RefSeq, Sep 2010]

Severe combined immunodeficiency due to CORO1A deficiency Pathogenic:2
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 08, 2018Loss-of-function variants in CORO1A are known to be pathogenic (PMID: 18836449, 25073507). This variant has been observed to segregate with combined immunodeficiency and selective T cell deficiency in a family (PMID: 25073507). This variant is also known as c.1077delC in the literature. ClinVar contains an entry for this variant (Variation ID: 157509). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Gln360Argfs*45) in the CORO1A gene. It is expected to result in an absent or disrupted protein product. For these reasons, this variant has been classified as Pathogenic. -
