Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001001479.4(SLC35E4):c.58G>A(p.Ala20Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00015 in 1,541,822 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict 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. A20E) has been classified as Uncertain significance.

Ambry Genetics

Dec 05, 2022

The c.58G>A (p.A20T) alteration is located in exon 1 (coding exon 1) of the SLC35E4 gene. This alteration results from a G to A substitution at nucleotide position 58, causing the alanine (A) at amino acid position 20 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
