Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1811C>T (p.A604V) alteration is located in exon 7 (coding exon 7) of the AGAP4 gene. This alteration results from a C to T substitution at nucleotide position 1811, causing the alanine (A) at amino acid position 604 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
