Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2021The c.131C>G (p.P44R) alteration is located in exon 3 (coding exon 1) of the LETM2 gene. This alteration results from a C to G substitution at nucleotide position 131, causing the proline (P) at amino acid position 44 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
