| Outline of Final Research Achievements |
Targeted resequencing was carried out 19 samples using TruSight One sequencing panels. which included 4,813 genes associated with known clinical phenotypes, as previously described We analyzed genes (including GH, GHR, STAT 5, STAT 3, IGF1R, IGF1, IGF2, IGFBP3, IGFALS, IRS1, and IRS2) associated with GH-IGF signals on the panel. We identified both heterozygous IGFALS mutation and IRS1 mutation in 1 case. Functional analysis revealed that both IRS1 mutation and IGFALS mutation result in growth failure. We are applying to publish the journal. Furthermore, heterozygous IGFBP5 mutation, and IGF 2 mutation were identified in each 1 case. We are under functional analysis for those.
