Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 09, 2021The c.484G>A (p.E162K) alteration is located in exon 5 (coding exon 4) of the DEF8 gene. This alteration results from a G to A substitution at nucleotide position 484, causing the glutamic acid (E) at amino acid position 162 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
