Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.245G>A (p.R82Q) alteration is located in exon 3 (coding exon 3) of the RHOF gene. This alteration results from a G to A substitution at nucleotide position 245, causing the arginine (R) at amino acid position 82 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
