Ambry Genetics

Sep 30, 2024

The c.140C>T (p.A47V) alteration is located in exon 2 (coding exon 1) of the ASPHD2 gene. This alteration results from a C to T substitution at nucleotide position 140, causing the alanine (A) at amino acid position 47 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
