Variant summary

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

The NM_001297563.2(TCEANC):​c.712C>G​(p.His238Asp) variant causes a missense change. The variant allele was found at a frequency of 0.000000916 in 1,091,843 control chromosomes in the GnomAD database, with no homozygous occurrence. There are no hemizygote samples in GnomAD. 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. H238Y) has been classified as Uncertain significance.
