Genes affected

ZNF423 (HGNC:16762): (zinc finger protein 423) The protein encoded by this gene is a nuclear protein that belongs to the family of Kruppel-like C2H2 zinc finger proteins. It functions as a DNA-binding transcription factor by using distinct zinc fingers in different signaling pathways. Thus, it is thought that this gene may have multiple roles in signal transduction during development. Mutations in this gene are associated with nephronophthisis-14 and Joubert syndrome-19. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2012]

The c.3443C>T (p.P1148L) alteration is located in exon 5 (coding exon 4) of the ZNF423 gene. This alteration results from a C to T substitution at nucleotide position 3443, causing the proline (P) at amino acid position 1148 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Collection Method: clinical testing

The P1148L variant in the ZNF423 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The P1148L variant is observed in 14/11518 (0.12%) alleles from individuals of Latino background, in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The P1148L variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved in mammals. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret P1148L as a variant of uncertain significance. -
