Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 23, 2021The c.1120G>A (p.V374M) alteration is located in exon 11 (coding exon 11) of the MFSD2B gene. This alteration results from a G to A substitution at nucleotide position 1120, causing the valine (V) at amino acid position 374 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
