Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 2P and 5B. PM2 BP4_Strong BP7

The NM_000215.4(JAK3):​c.108G>A​(p.Gly36Gly) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000933 in 1,608,126 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. G36G) has been classified as Likely benign. The gene JAK3 is included in the ClinGen Criteria Specification Registry.

Genes affected

JAK3 (HGNC:6193): (Janus kinase 3) The protein encoded by this gene is a member of the Janus kinase (JAK) family of tyrosine kinases involved in cytokine receptor-mediated intracellular signal transduction. It is predominantly expressed in immune cells and transduces a signal in response to its activation via tyrosine phosphorylation by interleukin receptors. Mutations in this gene are associated with autosomal SCID (severe combined immunodeficiency disease). [provided by RefSeq, Jul 2008]

JAK3 Gene-Disease associations (from GenCC):

• T-B+ severe combined immunodeficiency due to JAK3 deficiency

  Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: G2P, Laboratory for Molecular Medicine, Labcorp Genetics (formerly Invitae), ClinGen, Orphanet

ACMG classification

Specifications for JAK3 are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.75).
• BP7: Synonymous conserved (PhyloP=-1.67 with no splicing effect.
