Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 07, 2024The c.356A>T (p.E119V) alteration is located in exon 4 (coding exon 3) of the DEF8 gene. This alteration results from a A to T substitution at nucleotide position 356, causing the glutamic acid (E) at amino acid position 119 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
