• rs1166002350
• NM_016106.4:c.617C>T

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_016106.4(SCFD1):​c.617C>T​(p.Ala206Val) variant causes a missense change. The variant allele was found at a frequency of 0.000000702 in 1,425,002 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign 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. A206D) has been classified as Uncertain significance.
