The variant received -2 classification points (ACMG Germline Pathogenicity v2019). PM2BP4_Strong

The NM_000417.3(IL2RA):c.64+3326C>G variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

IL2RA (HGNC:6008): (interleukin 2 receptor subunit alpha) The interleukin 2 (IL2) receptor alpha (IL2RA) and beta (IL2RB) chains, together with the common gamma chain (IL2RG), constitute the high-affinity IL2 receptor. Homodimeric alpha chains (IL2RA) result in low-affinity receptor, while homodimeric beta (IL2RB) chains produce a medium-affinity receptor. Normally an integral-membrane protein, soluble IL2RA has been isolated and determined to result from extracellular proteolyisis. Alternately-spliced IL2RA mRNAs have been isolated, but the significance of each is presently unknown. Mutations in this gene are associated with interleukin 2 receptor alpha deficiency. Patients with severe Coronavirus Disease 2019 (COVID-19), the disease caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have significantly elevated levels of IL2R in their plasma. Similarly, serum IL-2R levels are found to be elevated in patients with different types of carcinomas. Certain IL2RA and IL2RB gene polymorphisms have been associated with lung cancer risk.

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript:

Our verdict: Likely_benign. The variant received -2 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	PM2Absent/extremely low in population databases		Absent from gnomAD (AR/unknown gene) — PM2; Absent from gnomAD at well-covered site (MOI: AR) (threshold 0.001) — PM2 moderate.
	BP4Computational evidence suggests no impact		Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Strong).
