Genetic Variant NM_015500.2:c.2003C>T (chr21-41889212-G-A) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_015500.2(C2CD2):c.2003C>T(p.Thr668Ile) variant causes a missense change. The variant allele was found at a frequency of 0.00000479 in 1,461,362 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. T668S) has been classified as Uncertain significance.
