not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2024The c.535G>A (p.A179T) alteration is located in exon 7 (coding exon 6) of the DCAF4 gene. This alteration results from a G to A substitution at nucleotide position 535, causing the alanine (A) at amino acid position 179 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
