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]

Collection Method: clinical testing

The c.332A>T (p.Q111L) alteration is located in exon 4 (coding exon 3) of the CSRP1 gene. This alteration results from a A to T substitution at nucleotide position 332, causing the glutamine (Q) at amino acid position 111 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
