The c.215A>G (p.Y72C) alteration is located in exon 4 (coding exon 4) of the DAPL1 gene. This alteration results from a A to G substitution at nucleotide position 215, causing the tyrosine (Y) at amino acid position 72 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
