Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 1P and 2B. PP2BP4_Moderate

The NM_000875.5(IGF1R):c.55C>G(p.Leu19Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000106 in 1,605,474 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L19F) has been classified as Uncertain significance.

Genes affected

IGF1R (HGNC:5465): (insulin like growth factor 1 receptor) This receptor binds insulin-like growth factor with a high affinity. It has tyrosine kinase activity. The insulin-like growth factor I receptor plays a critical role in transformation events. Cleavage of the precursor generates alpha and beta subunits. It is highly overexpressed in most malignant tissues where it functions as an anti-apoptotic agent by enhancing cell survival. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, May 2014]

IGF1R links:

IRAIN (HGNC:50365): (IGF1R antisense imprinted non-protein coding RNA) This gene expresses a long non-coding RNA in antisense to the insulin-like growth factor type I receptor (IGF1R) gene. This transcript is imprinted and expressed from the paternal allele. It interacts with chromatin and may promote long-range DNA interactions that influence the regulation of gene expression. [provided by RefSeq, Nov 2015]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PP2

Missense variant in the IGF1R gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 12 curated pathogenic missense variants (we use a threshold of 10). The gene has 19 curated benign missense variants. Trascript score misZ: 4.6449 (above the threshold of 3.09). GenCC associations: The gene is linked to growth delay due to insulin-like growth factor I resistance.

BP4

Computational evidence support a benign effect (MetaRNN=0.075280696).
