Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2022The c.146G>C (p.R49P) alteration is located in exon 1 (coding exon 1) of the MPV17L gene. This alteration results from a G to C substitution at nucleotide position 146, causing the arginine (R) at amino acid position 49 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
