Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.1942G>A (p.A648T) alteration is located in exon 18 (coding exon 15) of the DZIP1 gene. This alteration results from a G to A substitution at nucleotide position 1942, causing the alanine (A) at amino acid position 648 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
