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 GeneticsSep 15, 2021The c.494C>T (p.S165L) alteration is located in exon 5 (coding exon 5) of the MRO gene. This alteration results from a C to T substitution at nucleotide position 494, causing the serine (S) at amino acid position 165 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
