Variant 2-102718983-T-C details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_032718.5(MFSD9):c.862A>G(p.Ile288Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000041 in 1,461,890 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 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. I288T) has been classified as Likely benign.

The c.862A>G (p.I288V) alteration is located in exon 6 (coding exon 6) of the MFSD9 gene. This alteration results from a A to G substitution at nucleotide position 862, causing the isoleucine (I) at amino acid position 288 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
