CD5L

CD5 molecule like

Also known as: AIM, API6, CT-2, PRO229, SP-ALPHA, Spalpha, hAIM

The CD5L protein is secreted by macrophages and acts as a key regulator of lipid synthesis, fatty acid metabolism, and inflammatory responses, while also functioning as a pattern recognition receptor in immune defense. Mutations cause a neurodevelopmental disorder with variable features including intellectual disability, developmental delay, and neurological abnormalities. The condition follows autosomal recessive inheritance and this gene shows very low constraint against loss-of-function variants.

This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

GOFprediction above median
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.
