Genes affected

UNC80 (HGNC:26582): (unc-80 homolog, NALCN channel complex subunit) The protein encoded by this gene is a component of a voltage-independent 'leak' ion-channel complex, in which it performs essential functions, such as serving as a bridge between two other components (sodium leak channel non-selective and UNC79) and as a scaffold for Src kinases. Leak channels play an importnat role in establishment and maintenance of resting membrane potentials in neurons. Mutations in this gene are associated with congenital infantile encephalopathy, intellectual disability and growth issues. [provided by RefSeq, Aug 2016]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), UNC80. . Gene score misZ 5.5319 (greater than the threshold 3.09). Trascript score misZ 4.9857 (greater than threshold 3.09). GenCC has associacion of gene with hypotonia, infantile, with psychomotor retardation and characteristic facies 2, hypotonia, infantile, with psychomotor retardation and characteristic facies.

BP4

Computational evidence support a benign effect (MetaRNN=0.24767196).
