The c.368A>G (p.Y123C) alteration is located in exon 5 (coding exon 5) of the SPATA20 gene. This alteration results from a A to G substitution at nucleotide position 368, causing the tyrosine (Y) at amino acid position 123 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
