Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 06, 2023The c.590T>A (p.L197Q) alteration is located in exon 5 (coding exon 5) of the MRO gene. This alteration results from a T to A substitution at nucleotide position 590, causing the leucine (L) at amino acid position 197 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
