not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2022The c.953G>C (p.G318A) alteration is located in exon 7 (coding exon 7) of the MFSD7 gene. This alteration results from a G to C substitution at nucleotide position 953, causing the glycine (G) at amino acid position 318 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
