Submissions by phenotype

Polydactyly, postaxial, type A9 Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testing3billionMay 22, 2022The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: <0.001%). Stop-gained (nonsense): predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. A pathogenic variant is reported downstream of the variant. Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -
