Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4BS1_Supporting

The NM_020461.4(TUBGCP6):c.5426G>A(p.Arg1809His) variant causes a missense change. The variant allele was found at a frequency of 0.0000328 in 1,613,994 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1809C) has been classified as Uncertain significance.

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]

TUBGCP6 links:

SELENOO (HGNC:30395): (selenoprotein O) This gene encodes a selenoprotein that is localized to the mitochondria. It is the largest mammalian selenoprotein, containing the rare amino acid selenocysteine (Sec). Sec is encoded by the UGA codon, which normally signals translation termination. The 3' UTRs of selenoprotein mRNAs contain a conserved stem-loop structure, designated the Sec insertion sequence (SECIS) element, that is necessary for the recognition of UGA as a Sec codon, rather than as a stop signal. The exact function of this selenoprotein is not known, but it is thought to have redox activity. [provided by RefSeq, Dec 2016]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.37471077).

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000328 (48/1461758) while in subpopulation SAS AF = 0.000417 (36/86256). AF 95% confidence interval is 0.00031. There are 1 homozygotes in GnomAdExome4. There are 34 alleles in the male GnomAdExome4 subpopulation. Median coverage is 34. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
