Variant 1-234231548-G-T details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_173508.4(SLC35F3):c.415G>T(p.Val139Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000682 in 1,613,998 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 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. V139M) has been classified as Likely benign.

Ambry Genetics

Dec 28, 2023

The c.415G>T (p.V139L) alteration is located in exon 3 (coding exon 3) of the SLC35F3 gene. This alteration results from a G to T substitution at nucleotide position 415, causing the valine (V) at amino acid position 139 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
