ClinVar
Submissions by phenotype
not specified Uncertain:1
The c.1255G>T (p.D419Y) alteration is located in exon 10 (coding exon 9) of the ABCG2 gene. This alteration results from a G to T substitution at nucleotide position 1255, causing the aspartic acid (D) at amino acid position 419 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
