Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2022The c.817G>T (p.D273Y) alteration is located in exon 3 (coding exon 1) of the MFSD6 gene. This alteration results from a G to T substitution at nucleotide position 817, causing the aspartic acid (D) at amino acid position 273 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
