Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4BS1

The NM_000875.5(IGF1R):c.43G>A(p.Gly15Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00000621 in 1,609,894 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G15W) 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.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.32202286).

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.00000617 (9/1458620) while in subpopulation EAS AF = 0.000202 (8/39532). AF 95% confidence interval is 0.000101. There are 0 homozygotes in GnomAdExome4. There are 3 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
