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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -11 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=0.008615732).
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00171 (260/152276) while in subpopulation NFE AF= 0.00304 (207/68024). AF 95% confidence interval is 0.0027. There are 0 homozygotes in gnomad4. There are 117 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 10 AD,AR gene

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
