Ambry Genetics

Dec 21, 2023

The c.769C>T (p.P257S) alteration is located in exon 2 (coding exon 2) of the HOMEZ gene. This alteration results from a C to T substitution at nucleotide position 769, causing the proline (P) at amino acid position 257 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
