not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 07, 2024The c.1390G>A (p.E464K) alteration is located in exon 5 (coding exon 5) of the SCFD2 gene. This alteration results from a G to A substitution at nucleotide position 1390, causing the glutamic acid (E) at amino acid position 464 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
