Jan 29, 2024

The c.23G>A (p.C8Y) alteration is located in exon 1 (coding exon 1) of the DRICH1 gene. This alteration results from a G to A substitution at nucleotide position 23, causing the cysteine (C) at amino acid position 8 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
