Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2023The c.1267C>T (p.R423C) alteration is located in exon 6 (coding exon 6) of the MFSD9 gene. This alteration results from a C to T substitution at nucleotide position 1267, causing the arginine (R) at amino acid position 423 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
