Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 13, 2022The c.595C>T (p.R199C) alteration is located in exon 1 (coding exon 1) of the MFSD3 gene. This alteration results from a C to T substitution at nucleotide position 595, causing the arginine (R) at amino acid position 199 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
