The c.689A>G (p.K230R) alteration is located in exon 6 (coding exon 6) of the SAMSN1 gene. This alteration results from a A to G substitution at nucleotide position 689, causing the lysine (K) at amino acid position 230 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
