Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 13, 2021The c.938G>A (p.R313H) alteration is located in exon 6 (coding exon 6) of the MFSD9 gene. This alteration results from a G to A substitution at nucleotide position 938, causing the arginine (R) at amino acid position 313 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
