Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 26, 2024The c.427G>A (p.G143R) 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 427, causing the glycine (G) at amino acid position 143 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
