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 GeneticsJun 17, 2022The c.496G>A (p.A166T) alteration is located in exon 5 (coding exon 5) of the MRO gene. This alteration results from a G to A substitution at nucleotide position 496, causing the alanine (A) at amino acid position 166 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
