Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 2P and 7B. PM2 BP4_Strong BP6_Moderate BP7

The NM_020461.4(TUBGCP6):​c.3291G>T​(p.Val1097Val) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Synonymous variant affecting the same amino acid position (i.e. V1097V) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 34)
• Consequence: TUBGCP6 NM_020461.4 synonymous
• Clinical Significance: Likely benign criteria provided, single submitter B:1
• Conservation: PhyloP100: -1.24

Genes affected

TUBGCP6 (HGNC:18127): (tubulin gamma complex component 6) The protein encoded by this gene is part of a large multisubunit complex required for microtubule nucleation at the centrosome. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.57).
• BP6: Variant 22-50221068-C-A is Benign according to our data. Variant chr22-50221068-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 437151.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-1.24 with no splicing effect.
