not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2023The c.973A>T (p.M325L) alteration is located in exon 9 (coding exon 9) of the SERGEF gene. This alteration results from a A to T substitution at nucleotide position 973, causing the methionine (M) at amino acid position 325 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
