Genes affected
IGF1 (HGNC:5464): (insulin like growth factor 1) The protein encoded by this gene is similar to insulin in function and structure and is a member of a family of proteins involved in mediating growth and development. The encoded protein is processed from a precursor, bound by a specific receptor, and secreted. Defects in this gene are a cause of insulin-like growth factor I deficiency. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar processing to generate mature protein. [provided by RefSeq, Sep 2015]
LINC02456 (HGNC:53389): (long intergenic non-protein coding RNA 2456)

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.84).
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0182 (2766/152170) while in subpopulation NFE AF = 0.0246 (1674/68002). AF 95% confidence interval is 0.0236. There are 37 homozygotes in GnomAd4. There are 1276 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 37 AR,AD gene
