Genes affected

ZNF398 (HGNC:18373): (zinc finger protein 398) This gene encodes a member of the Kruppel family of C2H2-type zinc-finger transcription factor proteins. The encoded protein acts as a transcriptional activator. Two transcript variants encoding distinct isoforms have been identified for this gene. Other transcript variants have been described, but their full length sequence has not been determined. [provided by RefSeq, Jul 2008]

Jan 18, 2023

The c.391C>T (p.P131S) alteration is located in exon 2 (coding exon 2) of the ZNF398 gene. This alteration results from a C to T substitution at nucleotide position 391, causing the proline (P) at amino acid position 131 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
