Collection Method:clinical testing

The c.421C>G (p.L141V) alteration is located in exon 4 (coding exon 3) of the ARHGEF37 gene. This alteration results from a C to G substitution at nucleotide position 421, causing the leucine (L) at amino acid position 141 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
