Variant 14-57572018-A-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_001306087.2(SLC35F4):c.809T>C(p.Ile270Thr) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000618 in 1,456,344 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. 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. I270M) has been classified as Uncertain significance.

The c.806T>C (p.I269T) alteration is located in exon 5 (coding exon 5) of the SLC35F4 gene. This alteration results from a T to C substitution at nucleotide position 806, causing the isoleucine (I) at amino acid position 269 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
