Genes affected

AHCYL2 (HGNC:22204): (adenosylhomocysteinase like 2) The protein encoded by this gene acts as a homotetramer and may be involved in the conversion of S-adenosyl-L-homocysteine to L-homocysteine and adenosine. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2011]

The c.316G>A (p.V106I) alteration is located in exon 1 (coding exon 1) of the AHCYL2 gene. This alteration results from a G to A substitution at nucleotide position 316, causing the valine (V) at amino acid position 106 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
