Variant chr16-47313737-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_030790.5(ITFG1):c.889A>G(p.Met297Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000282 in 1,420,796 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. M297I) has been classified as Uncertain significance.

The c.889A>G (p.M297V) alteration is located in exon 9 (coding exon 9) of the ITFG1 gene. This alteration results from a A to G substitution at nucleotide position 889, causing the methionine (M) at amino acid position 297 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
