Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.850G>A (p.G284R) alteration is located in exon 8 (coding exon 8) of the MTHFSD gene. This alteration results from a G to A substitution at nucleotide position 850, causing the glycine (G) at amino acid position 284 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
