Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.110G>C (p.R37P) alteration is located in exon 2 (coding exon 2) of the SLC50A1 gene. This alteration results from a G to C substitution at nucleotide position 110, causing the arginine (R) at amino acid position 37 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
