Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BP4_StrongBS1

The NM_000875.5(IGF1R):​c.2570A>C​(p.Asn857Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000186 in 1,613,936 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. 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. N857S) 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 Gene-Disease associations (from GenCC):
  • growth delay due to insulin-like growth factor I resistance

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.047744125).
BS1
Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000198 (29/1461716) while in subpopulation SAS AF = 0.000325 (28/86256). AF 95% confidence interval is 0.00023. There are 0 homozygotes in GnomAdExome4. There are 24 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
