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]

Collection Method: clinical testing

The c.560T>C (p.L187S) alteration is located in exon 9 (coding exon 5) of the MIPOL1 gene. This alteration results from a T to C substitution at nucleotide position 560, causing the leucine (L) at amino acid position 187 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
