Genes affected
HPDL (HGNC:28242): (4-hydroxyphenylpyruvate dioxygenase like) The protein encoded by this intronless gene localizes to mitochondria, where it may function as 4-hydroxyphenylpyruvate dioxygenase. Clinical studies have identified several bi-allelic variants in this gene that lower the level of the encoded protein and lead to a clinically variable form of pediatric-onset spastic movement disorder.

ACMG classification
Classification was made for transcript
Our verdict: Uncertain_significance. The variant received 3 ACMG points.
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 21 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Gene score misZ: 0.93302 (below the threshold of 3.09). Trascript score misZ: -1.2259 (below the threshold of 3.09). GenCC associations: The gene is linked to Leigh syndrome, neurodevelopmental disorder with progressive spasticity and brain white matter abnormalities.
