Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.2129C>T (p.A710V) alteration is located in exon 17 (coding exon 17) of the AFAP1L2 gene. This alteration results from a C to T substitution at nucleotide position 2129, causing the alanine (A) at amino acid position 710 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
