Description

The c.221A>C (p.D74A) alteration is located in exon 1 (coding exon 1) of the HOXB2 gene. This alteration results from a A to C substitution at nucleotide position 221, causing the aspartic acid (D) at amino acid position 74 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
