Ambry Genetics

Jul 26, 2024

The c.527A>G (p.Y176C) alteration is located in exon 5 (coding exon 4) of the HMGXB4 gene. This alteration results from a A to G substitution at nucleotide position 527, causing the tyrosine (Y) at amino acid position 176 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
