Variant names:

• chr5-65660838-G-A
• rs375637923
• NM_024941.4:c.838G>A

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_024941.4(TRAPPC13):​c.838G>A​(p.Val280Ile) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. 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. V280L) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: TRAPPC13 NM_024941.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 9.52
• Publications: 0 publications found
