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 -15 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), IGF1R. . Trascript score misZ: 4.6449 (greater than threshold 3.09). The gene has 12 curated pathogenic missense variants (we use a threshold of 10). The gene has 19 curated benign missense variants. GenCC has associacion of the gene with growth delay due to insulin-like growth factor I resistance.
BP4
Computational evidence support a benign effect (MetaRNN=0.014846861).
BP6
Variant 15-98899536-G-A is Benign according to our data. Variant chr15-98899536-G-A is described in ClinVar as [Benign]. Clinvar id is 716221.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr15-98899536-G-A is described in Lovd as [Likely_benign].
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00165 (251/152318) while in subpopulation AFR AF= 0.00469 (195/41572). AF 95% confidence interval is 0.00415. There are 0 homozygotes in gnomad4. There are 116 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
