Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2021The c.1294G>A (p.V432I) alteration is located in exon 6 (coding exon 6) of the MFSD9 gene. This alteration results from a G to A substitution at nucleotide position 1294, causing the valine (V) at amino acid position 432 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
