Genes linked to Camptodactyly-tall stature-scoliosis-hearing loss syndrome
FGFR3: Fibroblast growth factor receptor 3
It normally restrains growth-plate chondrocyte proliferation while regulating multiple developmental pathways. Activating germline variants cause achondroplasia and related skeletal dysplasias, while somatic activating alterations are common in bladder cancer and some other tumors.
1 disease-causing and 7 uncertain variants in FGFR3 are linked to Camptodactyly-tall stature-scoliosis-hearing loss syndrome.
Known disease-causing variants in Camptodactyly-tall stature-scoliosis-hearing loss syndrome
| Variant | Position | Protein part | Clinical label |
|---|---|---|---|
| FGFR3 N540D | 540 | Protein kinase | Disease-causing (★★) |

About this data
Variant–disease links come from ClinVar, Open Targets and UniProt, pooled from the latest public CATVariant analysis of each human protein. Evidence scores use the ACMG/AMP Bayesian points scale with computable criteria only (position among known disease variants, rarity in gnomAD, calibrated predictors, deep mutational scanning); there is no family or patient data, so they prioritise variants for expert review and never classify them.
