Genes affected
MAPRE3 (HGNC:6892): (microtubule associated protein RP/EB family member 3) The protein encoded by this gene is a member of the RP/EB family of genes. The protein localizes to the cytoplasmic microtubule network and binds APCL, a homolog of the adenomatous polyposis coli tumor suppressor gene. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 18, 2024The c.248A>G (p.K83R) alteration is located in exon 3 (coding exon 2) of the MAPRE3 gene. This alteration results from a A to G substitution at nucleotide position 248, causing the lysine (K) at amino acid position 83 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
