Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2022The c.919A>G (p.M307V) alteration is located in exon 10 (coding exon 10) of the SLC47A1 gene. This alteration results from a A to G substitution at nucleotide position 919, causing the methionine (M) at amino acid position 307 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
