Genes affected
LINS1 (HGNC:30922): (lines homolog 1) The Drosophila segment polarity gene lin encodes a protein, lines, which plays important roles in development of the epidermis and hindgut. This gene encodes a protein containing a lines-like domain. This gene is located on chromosome 15 and clustered with the gene encoding ankyrin repeat and SOCS box-containing protein 7. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2017]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.R725C variant (also known as c.2173C>T), located in coding exon 6 of the LINS gene, results from a C to T substitution at nucleotide position 2173. The arginine at codon 725 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
