The c.551G>T (p.G184V) alteration is located in exon 4 (coding exon 4) of the SPATA31C1 gene. This alteration results from a G to T substitution at nucleotide position 551, causing the glycine (G) at amino acid position 184 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
