Genes affected
CD3E (HGNC:1674): (CD3 epsilon subunit of T-cell receptor complex) The protein encoded by this gene is the CD3-epsilon polypeptide, which together with CD3-gamma, -delta and -zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T-cell receptor-CD3 complex. This complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. The genes encoding the epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. The epsilon polypeptide plays an essential role in T-cell development. Defects in this gene cause immunodeficiency. This gene has also been linked to a susceptibility to type I diabetes in women. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 10 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.028846154 fraction of the gene. Cryptic splice site detected, with MaxEntScore 4.3, offset of 48, new splice context is: ttgGTgggt. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
PP5
Variant 11-118312171-G-A is Pathogenic according to our data. Variant chr11-118312171-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 835442.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Significance:Likely pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change affects a donor splice site in intron 5 of the CD3E gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in CD3E are known to be pathogenic (PMID: 8490660, 15546002). This variant is present in population databases (rs201543770, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with CD3E-related conditions. ClinVar contains an entry for this variant (Variation ID: 835442). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -

Significance:Likely pathogenic
Review Status:criteria provided, single submitter
Collection Method:curation

Canonical splice site variant in CD3E (c.103+1G>A), abolishes the donor site of intron 2. Expected to result in aberrant splicing and loss of function (PVS1), which is a known mechanism in CD3E-related immunodeficiency (OMIM #615615). Variant is absent from population databases (PM2) and has been reported in affected individuals. Detected in homozygous state. Classified as Likely Pathogenic. Meets ACMG criteria: PVS1, PM2, PP4. -
