Genetic Variant SETD4:p.Thr343Ile (chr21-36040611-G-A) – ACMG Classification: Uncertain_significance (4 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_017438.5(SETD4):c.1028C>T(p.Thr343Ile) variant causes a missense change. The variant allele was found at a frequency of 0.0000109 in 1,461,610 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. T343R) has been classified as Uncertain significance.
