Genes affected
ENOSF1 (HGNC:30365): (enolase superfamily member 1) This gene can encode a mitochondrial enzyme that is thought to convert L-fuconate to 2-keto-3-deoxy-L-fuconate. This locus was originally identified as the source of antisense RNAs of the adjacent thymidylate synthase gene. Splice variants at this locus may contain an alternate 3' exon that is complementary to the 3'UTR and terminal intron of the thymidylate synthase (TS) RNA and may downregulate TS expression.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2024The c.1001T>C (p.I334T) alteration is located in exon 12 (coding exon 12) of the ENOSF1 gene. This alteration results from a T to C substitution at nucleotide position 1001, causing the isoleucine (I) at amino acid position 334 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
