Variant 2-131480159-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 1P and 1B. PP2BP4

The NM_080386.4(TUBA3D):c.466C>T(p.Arg156Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R156Q) has been classified as Uncertain significance.

Genes affected

TUBA3D (HGNC:24071): (tubulin alpha 3d) This gene encodes a member of the alpha tubulin family. Tubulin is a major component of microtubules, which are composed of alpha- and beta-tubulin heterodimers and microtubule-associated proteins in the cytoskeleton. Microtubules maintain cellular structure, function in intracellular transport, and play a role in spindle formation during mitosis. [provided by RefSeq, Oct 2011]

MZT2A (HGNC:33187): (mitotic spindle organizing protein 2A) Located in centrosome; cytosol; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
