Genetic Variant LIFR:p.Asp578Asn (chr5-38496533-ATC-GTT) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is The variant received 1 classification points (ACGS-UK Somatic Oncogenicity v2025). O3_ModerateB2_Supporting

The NM_001127671.2(LIFR):c.1732_1734delGATinsAAC (p.Asp578Asn) variant causes a missense change. The gene LIFR is a tumor suppressor gene (CancerMine: 13 TSG, 5 oncogene, 1 driver citations). The gene LIFR is a known oncogene (CancerMine: 13 TSG, 5 oncogene, 1 driver citations). The gene LIFR is a cancer driver gene (CancerMine: 13 TSG, 5 oncogene, 1 driver citations). Note: allele frequency estimates from gnomAD may be inaccurate for this variant type (MNP or indel longer than 3 bp) due to technology limitations. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.D578N: Benign (ClinVar VariationId 353625, 2 stars) This exact variant is curated in the UniProt human variants database as Uncertain Significance; it is also listed as a COSMIC curated somatic variant.

Genes affected

LIFR (HGNC:6597): (LIF receptor subunit alpha) This gene encodes a protein that belongs to the type I cytokine receptor family. This protein combines with a high-affinity converter subunit, gp130, to form a receptor complex that mediates the action of the leukemia inhibitory factor, a polyfunctional cytokine that is involved in cellular differentiation, proliferation and survival in the adult and the embryo. Mutations in this gene cause Schwartz-Jampel syndrome type 2, a disease belonging to the group of the bent-bone dysplasias. A translocation that involves the promoter of this gene, t(5;8)(p13;q12) with the pleiomorphic adenoma gene 1, is associated with salivary gland pleiomorphic adenoma, a common type of benign epithelial tumor of the salivary gland. Multiple splice variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jun 2018]

Classification according to ACGS-UK Somatic Oncogenicity v2025

Classification was made for transcript:

Our verdict: Uncertain_significance. The variant received 1 points.

Show applied only (2)

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
