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 -9 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=0.04472822).

BP6

Variant 15-98957185-G-A is Benign according to our data. Variant chr15-98957185-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 721865.Status of the report is criteria_provided_single_submitter, 1 stars.

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000525 (8/152352) while in subpopulation EAS AF= 0.000578 (3/5186). AF 95% confidence interval is 0.000157. There are 0 homozygotes in gnomad4. There are 3 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
