Genes affected
AHCYL1 (HGNC:344): (adenosylhomocysteinase like 1) The protein encoded by this gene interacts with inositol 1,4,5-trisphosphate receptor, type 1 and may be involved in the conversion of S-adenosyl-L-homocysteine to L-homocysteine and adenosine. Several transcript variants encoding two 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 GeneticsDec 06, 2024The c.140A>C (p.D47A) alteration is located in exon 2 (coding exon 2) of the AHCYL1 gene. This alteration results from a A to C substitution at nucleotide position 140, causing the aspartic acid (D) at amino acid position 47 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
