Genetic Variant SLC35E2B:p.Ser289Asn (chr1-1668441-C-T) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001290264.2(SLC35E2B):c.866G>A(p.Ser289Asn) variant causes a missense change. The variant allele was found at a frequency of 0.0000521 in 1,613,472 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 10/16 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. S289T) has been classified as Uncertain significance.
