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 made for transcript

Verdict is Uncertain_significance. Variant got 5 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
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). GenCC has associacion of gene with growth delay due to insulin-like growth factor I resistance.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.85
