Genes affected

ZFP91 (HGNC:14983): (ZFP91 zinc finger protein, atypical E3 ubiquitin ligase) The protein encoded by this gene is a member of the zinc finger family of proteins. The gene product contains C2H2-type domains, which are the classical zinc finger domains found in numerous nucleic acid-binding proteins. This protein functions as a regulator of the non-canonical NF-kappaB pathway in lymphotoxin-beta receptor signaling. Alternative splicing results in multiple transcript variants. A read-through transcript variant composed of ZFP91 and the downstream CNTF gene sequence has been identified, but it is thought to be non-coding. Read-through transcription of ZFP91 and CNTF has also been observed in mouse. A ZFP91-related pseudogene has also been identified on chromosome 2. [provided by RefSeq, Oct 2010]

The c.502A>G (p.T168A) alteration is located in exon 3 (coding exon 3) of the ZFP91 gene. This alteration results from a A to G substitution at nucleotide position 502, causing the threonine (T) at amino acid position 168 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
