Collection Method: clinical testing

The c.112G>A (p.E38K) alteration is located in exon 1 (coding exon 1) of the HEXIM1 gene. This alteration results from a G to A substitution at nucleotide position 112, causing the glutamic acid (E) at amino acid position 38 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
