Genes affected

RNF212 (HGNC:27729): (ring finger protein 212) This gene encodes a RING finger protein that may function as a ubiquitin ligase. The encoded protein may be involved in meiotic recombination. This gene is located within a linkage disequilibrium block and polymorphisms in this gene may influence recombination rates. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Oct 2010]

RNF212 (HGNC:):

The c.752A>T (p.K251I) alteration is located in exon 10 (coding exon 10) of the RNF212 gene. This alteration results from a A to T substitution at nucleotide position 752, causing the lysine (K) at amino acid position 251 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
