Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1750G>T (p.D584Y) alteration is located in exon 4 (coding exon 3) of the DCLK3 gene. This alteration results from a G to T substitution at nucleotide position 1750, causing the aspartic acid (D) at amino acid position 584 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
