Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 27, 2021The c.929T>C (p.L310P) alteration is located in exon 8 (coding exon 8) of the DDX43 gene. This alteration results from a T to C substitution at nucleotide position 929, causing the leucine (L) at amino acid position 310 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
