LHX2
Chr 9LIM homeobox 2
LHX2 encodes a transcription factor that regulates cell differentiation in developing lymphoid and neural tissues and acts as a transcriptional activator. Mutations cause autosomal dominant developmental abnormalities affecting the nervous system and other organ systems. The gene is highly constrained against loss-of-function variants (pLI 0.99, LOEUF 0.22), indicating that even single functional copies are critical for normal development.
Strong evidence — appropriate for clinical testing

Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Moderately missense-constrained (top ~2.5%)
The highest-scoring mechanism for this gene is loss-of-function (haploinsufficiency).
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
