Genes affected

GLI1 (HGNC:4317): (GLI family zinc finger 1) This gene encodes a member of the Kruppel family of zinc finger proteins. The encoded transcription factor is activated by the sonic hedgehog signal transduction cascade and regulates stem cell proliferation. The activity and nuclear localization of this protein is negatively regulated by p53 in an inhibitory loop. Multiple transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

Polydactyly, postaxial, type A8 Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	3billion	Jan 03, 2022	Stop-gained (nonsense): predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant (PVS1_VS). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000004, PM2_M). The variant has been reported to be associated with GLI1 related disorder (ClinVar ID: VCV000561215, PMID:28973407). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -
