The c.605G>A (p.R202Q) alteration is located in exon 5 (coding exon 5) of the SPEF2 gene. This alteration results from a G to A substitution at nucleotide position 605, causing the arginine (R) at amino acid position 202 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
