Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 17, 2023The c.398G>A (p.R133H) alteration is located in exon 2 (coding exon 1) of the SLCO4A1 gene. This alteration results from a G to A substitution at nucleotide position 398, causing the arginine (R) at amino acid position 133 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
