INSL4

Chr 9

insulin like 4

Also known as: EPIL, PLACENTIN

The insulin-like 4 protein functions in trophoblast development during early placental formation and regulates bone formation. No established disease associations have been reported for INSL4 mutations in current medical literature. This gene shows very low constraint against loss-of-function variants, suggesting that complete loss of function may be tolerated.

The highest-scoring mechanism for this gene is dominant-negative.

DNprediction above median

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
