Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.383G>A (p.R128H) alteration is located in exon 3 (coding exon 2) of the MRPL14 gene. This alteration results from a G to A substitution at nucleotide position 383, causing the arginine (R) at amino acid position 128 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
