Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 09, 2021The c.65A>T (p.H22L) alteration is located in exon 1 (coding exon 1) of the MRM1 gene. This alteration results from a A to T substitution at nucleotide position 65, causing the histidine (H) at amino acid position 22 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
