Genes affected
MRO (HGNC:24121): (maestro) This gene is specifically transcribed in males before and after differentiation of testis, and the encoded protein may play an important role in a mammalian sex determination. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2024The c.26A>G (p.Q9R) alteration is located in exon 2 (coding exon 2) of the MRO gene. This alteration results from a A to G substitution at nucleotide position 26, causing the glutamine (Q) at amino acid position 9 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
