Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 2P and 5B. PM1BP4BS1

The NM_000875.5(IGF1R):​c.3737G>A​(p.Arg1246His) variant causes a missense change. The variant allele was found at a frequency of 0.0000248 in 1,614,200 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1246C) has been classified as Uncertain significance.

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]
SYNM-AS1 (HGNC:55421): (SYNM antisense RNA 1)

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

PM1
In a domain Protein kinase (size 275) in uniprot entity IGF1R_HUMAN there are 13 pathogenic changes around while only 0 benign (100%) in NM_000875.5
BP4
Computational evidence support a benign effect (MetaRNN=0.3646808).
BS1
Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.0000656 (10/152338) while in subpopulation EAS AF = 0.000386 (2/5176). AF 95% confidence interval is 0.0000684. There are 0 homozygotes in GnomAd4. There are 6 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
