Gene: IL2RG (HGNC:6010)
Evidence Code: PVS1 — Original ACMG Summary
Null variant (nonsense, frameshift, canonical +/−1 or 2 splice sites, initiation codon, single or multi-exon deletion) in a gene where loss of function (LOF) is a known mechanism of disease.
Caveats:
 • Beware of genes where LOF is not a known disease mechanism (e.g. GFAP, MYH7).
 • Use caution interpreting LOF variants at the extreme 3’ end of a gene.
 • Use caution with splice variants that are predicted to lead to exon skipping but leave the remainder of the protein intact.
 • Use caution in the presence of multiple transcripts.
Gene: IL2RG (HGNC:6010)
Evidence Code: PVS1 — Very Strong
Modification Type: General recommendation,Gene-specific
Use ClinGen SVI recommendations for loss of function criterion (Tayoun et al., 2018 (PMID: 30192042)) with one specification:




PVS1 at default strength (Very Strong) can be applied to variants not predicted to undergo nonsense-mediated decay but truncating the transmembrane domain (which begins at amino acid 255) or any distal region (i.e. cytoplasmic domain) due to the lack of functionality of the protein expressed with this defect.

Evidence Code: PS4 — Original ACMG Summary
The prevalence of the variant in affected individuals is significantly increased compared to the prevalence in controls.

Note 2: In instances of very rare variants where case-control studies may not reach statistical significance, the prior observation of the variant in multiple unrelated patients with the same phenotype, and its absence in controls, may be used as moderate level of evidence.

A synonymous variant for which splicing prediction algorithms predict no impact to the splice consensus sequence nor the creation of a new splice site AND the nucleotide is not highly conserved.
Gene: IL2RG (HGNC:6010)
Evidence Code: BP7 — Supporting
Modification Type: General recommendation
Applicable to both synonymous variants and deep intronic variants affecting nucleotides at or beyond the +7 (donor) and -21 (acceptor) positions.


The variant should be predicted not to impact splicing by at least two out of three 
in silico
 tools (freely available tools include GeneSplicer, MaxEntScan, NNSplice, SpliceAI, Splicing Sequences Finder (SSF), and varSEAK).


Given the potential for poor conservation of genes related to T cell and B cell development among vertebrates, nucleotide conservation is 
not required
 in order to apply BP7.
