Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2023The c.643G>T (p.V215L) alteration is located in exon 2 (coding exon 1) of the SLCO4A1 gene. This alteration results from a G to T substitution at nucleotide position 643, causing the valine (V) at amino acid position 215 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
