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]

The c.287A>G (p.K96R) alteration is located in exon 3 (coding exon 3) of the MRO gene. This alteration results from a A to G substitution at nucleotide position 287, causing the lysine (K) at amino acid position 96 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
