Ambry Genetics

Aug 02, 2022

The c.143C>T (p.A48V) alteration is located in exon 2 (coding exon 1) of the C1QTNF9 gene. This alteration results from a C to T substitution at nucleotide position 143, causing the alanine (A) at amino acid position 48 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
