"In Indian Wilson disease patients, GRIN2B and DRD4…" — Prakriti Jana (#c823)

Card #c823IR // #c823SynthesisThesis

In Indian Wilson disease patients, GRIN2B and DRD4 polymorphisms act as cognitive modifier genes — the GRIN2B T/T genotype predicts poorer immediate recall and conflict resolution but protects verbal fluency, while the DRD4 C allele protects executive and spatial function yet risks delayed recall when homozygous. Allele effects are domain-specific, never uniformly good or bad.

[Use when]

Genes don't confer "better" or "worse" cognition — effects are domain-specific; the same allele can protect one faculty while eroding another.

[Why it matters]

A clean demonstration that a single allele can be protective and risky at once depending on the cognitive domain — the reason gene-phenotype findings resist headline simplification.
