The c.1302C>G (p.S434R) alteration is located in exon 10 (coding exon 10) of the FAM189A1 gene. This alteration results from a C to G substitution at nucleotide position 1302, causing the serine (S) at amino acid position 434 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
