Collection Method: clinical testing

The c.1249G>T (p.D417Y) alteration is located in exon 7 (coding exon 7) of the CUZD1 gene. This alteration results from a G to T substitution at nucleotide position 1249, causing the aspartic acid (D) at amino acid position 417 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
