Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 17, 2023The c.1039C>T (p.L347F) alteration is located in exon 8 (coding exon 8) of the MTHFSD gene. This alteration results from a C to T substitution at nucleotide position 1039, causing the leucine (L) at amino acid position 347 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
