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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 30, 2024The c.5C>G (p.S2W) alteration is located in exon 1 (coding exon 1) of the AHCYL2 gene. This alteration results from a C to G substitution at nucleotide position 5, causing the serine (S) at amino acid position 2 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
