Genes affected

RC3H1 (HGNC:29434): (ring finger and CCCH-type domains 1) This gene encodes a protein containing RING-type and C3H1-type zinc finger motifs. The encoded protein recognizes and binds to a constitutive decay element (CDE) in the 3' UTR of mRNAs, leading to mRNA deadenylation and degradation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

The c.2861A>G (p.H954R) alteration is located in exon 16 (coding exon 16) of the RC3H1 gene. This alteration results from a A to G substitution at nucleotide position 2861, causing the histidine (H) at amino acid position 954 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
