Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 02, 2024The c.435G>C (p.Q145H) alteration is located in exon 1 (coding exon 1) of the MRM1 gene. This alteration results from a G to C substitution at nucleotide position 435, causing the glutamine (Q) at amino acid position 145 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
