Genetic Variant TUBGCP6:p.Ser733Asn (chr22-50224213-C-T) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_020461.4(TUBGCP6):c.2198G>A(p.Ser733Asn) variant causes a missense change. The variant allele was found at a frequency of 0.0000149 in 1,614,068 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. S733T) has been classified as Uncertain significance.
