Genes affected

ZNF346 (HGNC:16403): (zinc finger protein 346) The protein encoded by this gene is a nucleolar, zinc finger protein that preferentially binds to double-stranded (ds) RNA or RNA/DNA hybrids, rather than DNA alone. Mutational studies indicate that the zinc finger domains are not only essential for dsRNA binding, but are also required for its nucleolar localization. The encoded protein may be involved in cell growth and survival. It plays a role in protecting neurons by inhibiting cell cycle re-entry via stimulation of p21 gene expression. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Apr 2015]

The c.35C>T (p.A12V) alteration is located in exon 1 (coding exon 1) of the ZNF346 gene. This alteration results from a C to T substitution at nucleotide position 35, causing the alanine (A) at amino acid position 12 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
