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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2023The c.266C>T (p.P89L) alteration is located in exon 1 (coding exon 1) of the TUBA3D gene. This alteration results from a C to T substitution at nucleotide position 266, causing the proline (P) at amino acid position 89 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
