Genes affected

CSRP1 (HGNC:2469): (cysteine and glycine rich protein 1) This gene encodes a member of the cysteine-rich protein (CSRP) family. This gene family includes a group of LIM domain proteins, which may be involved in regulatory processes important for development and cellular differentiation. The LIM/double zinc-finger motif found in this gene product occurs in proteins with critical functions in gene regulation, cell growth, and somatic differentiation. Alternatively spliced transcript variants have been described. [provided by RefSeq, Aug 2010]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.362G>A (p.R121Q) alteration is located in exon 4 (coding exon 3) of the CSRP1 gene. This alteration results from a G to A substitution at nucleotide position 362, causing the arginine (R) at amino acid position 121 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
