Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.404G>A (p.G135D) alteration is located in exon 1 (coding exon 1) of the MFSD3 gene. This alteration results from a G to A substitution at nucleotide position 404, causing the glycine (G) at amino acid position 135 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
