FGL1

Chr 8

fibrinogen like 1

Also known as: HFREP1, HP-041, HPS, LFIRE-1, LFIRE1

Fibrinogen-like 1 encodes a secreted protein that inhibits T-cell activation by binding to the LAG3 receptor and also promotes hepatocyte growth. This gene is not constrained against loss-of-function variants and is not currently associated with any established Mendelian disorders in pediatric neurology.

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.
