Collection Method: clinical testing

The c.644C>G (p.A215G) alteration is located in exon 2 (coding exon 2) of the ERICH5 gene. This alteration results from a C to G substitution at nucleotide position 644, causing the alanine (A) at amino acid position 215 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
