Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2024The c.238A>G (p.R80G) alteration is located in exon 2 (coding exon 2) of the MTHFD2L gene. This alteration results from a A to G substitution at nucleotide position 238, causing the arginine (R) at amino acid position 80 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
