Variant 15-89750607-C-G 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_018670.4(MESP1):c.625G>C(p.Gly209Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000287 in 1,395,548 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. G209G) has been classified as Likely benign.

The c.625G>C (p.G209R) alteration is located in exon 1 (coding exon 1) of the MESP1 gene. This alteration results from a G to C substitution at nucleotide position 625, causing the glycine (G) at amino acid position 209 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
