Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.1558G>C (p.G520R) alteration is located in exon 10 (coding exon 10) of the MFSD7 gene. This alteration results from a G to C substitution at nucleotide position 1558, causing the glycine (G) at amino acid position 520 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
