Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.460C>G (p.R154G) alteration is located in exon 3 (coding exon 3) of the MFSD1 gene. This alteration results from a C to G substitution at nucleotide position 460, causing the arginine (R) at amino acid position 154 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
