Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate

The NM_000875.5(IGF1R):c.59C>T(p.Ser20Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000255 in 1,609,984 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. S20S) has been classified as Likely benign.

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.
