• rs375144081
• NM_152903.5:c.1321G>C

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 4P and 4B. PP3_Strong BS2

The NM_152903.5(KBTBD6):​c.1321G>C​(p.Gly441Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00000958 in 1,461,886 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. G441W) has been classified as Uncertain significance.
