Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2024The c.163T>C (p.S55P) alteration is located in exon 2 (coding exon 2) of the MTHFD2L gene. This alteration results from a T to C substitution at nucleotide position 163, causing the serine (S) at amino acid position 55 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
