Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2021The c.313G>A (p.G105R) alteration is located in exon 1 (coding exon 1) of the MEPCE gene. This alteration results from a G to A substitution at nucleotide position 313, causing the glycine (G) at amino acid position 105 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
