Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 22, 2021The c.1033G>A (p.G345R) alteration is located in exon 3 (coding exon 1) of the MFSD6 gene. This alteration results from a G to A substitution at nucleotide position 1033, causing the glycine (G) at amino acid position 345 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
