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.220G>A (p.G74R) alteration is located in exon 3 (coding exon 2) of the CSRP1 gene. This alteration results from a G to A substitution at nucleotide position 220, causing the glycine (G) at amino acid position 74 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
