• rs2031330862
• NM_005860.3:c.587G>C

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2 PP3

The NM_005860.3(FSTL3):​c.587G>C​(p.Arg196Pro) variant causes a missense change. The variant allele was found at a frequency of 0.00000125 in 1,596,208 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R196L) has been classified as Uncertain significance.
