Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 06, 2022The c.821A>T (p.D274V) alteration is located in exon 4 (coding exon 4) of the AZGP1 gene. This alteration results from a A to T substitution at nucleotide position 821, causing the aspartic acid (D) at amino acid position 274 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
