Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2021The c.404A>T (p.N135I) alteration is located in exon 3 (coding exon 3) of the MTHFD2L gene. This alteration results from a A to T substitution at nucleotide position 404, causing the asparagine (N) at amino acid position 135 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
