Genes affected

CAPZA1 (HGNC:1488): (capping actin protein of muscle Z-line subunit alpha 1) CAPZA1 is a member of the F-actin capping protein alpha subunit family. This gene encodes the alpha subunit of the barbed-end actin binding protein. The protein regulates growth of the actin filament by capping the barbed end of growing actin filaments.

ST7L (HGNC:18441): (suppression of tumorigenicity 7 like) This gene was identified by its similarity to the ST7 tumor suppressor gene found in the chromosome 7q31 region. This gene is clustered in a tail-to-tail manner with the WNT2B gene in a chromosomal region known to be deleted and rearranged in a variety of cancers. Several transcript variants encoding many different isoforms have been described, but some have not been fully characterized. [provided by RefSeq, Feb 2011]

Collection Method:clinical testing

The c.13G>A (p.D5N) alteration is located in exon 1 (coding exon 1) of the CAPZA1 gene. This alteration results from a G to A substitution at nucleotide position 13, causing the aspartic acid (D) at amino acid position 5 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
