Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 11, 2023The c.973A>C (p.I325L) alteration is located in exon 6 (coding exon 6) of the MFSD9 gene. This alteration results from a A to C substitution at nucleotide position 973, causing the isoleucine (I) at amino acid position 325 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
