Genes affected
MIPOL1 (HGNC:21460): (mirror-image polydactyly 1) This gene encodes a coiled-coil domain-containing protein. The encoded protein may function as a tumor suppressor. A translocation that results in truncation of the protein encoded by this locus has been associated with mirror-image polydactyly, also known as Laurin-Sandrow Syndrome. Alternatively spliced transcript variants have been described. [provided by RefSeq, Sep 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2023The c.23T>A (p.I8K) alteration is located in exon 6 (coding exon 2) of the MIPOL1 gene. This alteration results from a T to A substitution at nucleotide position 23, causing the isoleucine (I) at amino acid position 8 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
