The c.377C>T (p.A126V) alteration is located in exon 4 (coding exon 4) of the HYPK gene. This alteration results from a C to T substitution at nucleotide position 377, causing the alanine (A) at amino acid position 126 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
