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 27, 2024The c.118G>C (p.A40P) alteration is located in exon 1 (coding exon 1) of the AHCYL2 gene. This alteration results from a G to C substitution at nucleotide position 118, causing the alanine (A) at amino acid position 40 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
