Genes affected

LMX1B (HGNC:6654): (LIM homeobox transcription factor 1 beta) This gene encodes a member of LIM-homeodomain family of proteins containing two N-terminal zinc-binding LIM domains, 1 homeodomain, and a C-terminal glutamine-rich domain. It functions as a transcription factor, and is essential for the normal development of dorsal limb structures, the glomerular basement membrane, the anterior segment of the eye, and dopaminergic and serotonergic neurons. Mutations in this gene are associated with nail-patella syndrome. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2010]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.115C>T (p.P39S) alteration is located in exon 1 (coding exon 1) of the LMX1B gene. This alteration results from a C to T substitution at nucleotide position 115, causing the proline (P) at amino acid position 39 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
