Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2 BP4

The NM_016261.4(TUBD1):​c.227T>G​(p.Met76Arg) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict 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. M76T) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 31)
• Consequence: TUBD1 NM_016261.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 4.26

Genes affected

TUBD1 (HGNC:16811): (tubulin delta 1) Predicted to enable GTP binding activity. Predicted to be a structural constituent of cytoskeleton. Predicted to be involved in microtubule cytoskeleton organization; mitotic cell cycle; and positive regulation of smoothened signaling pathway. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.
