Genes affected

SCARA3 (HGNC:19000): (scavenger receptor class A member 3) This gene encodes a macrophage scavenger receptor-like protein. This protein has been shown to deplete reactive oxygen species, and thus play an important role in protecting cells from oxidative stress. The expression of this gene is induced by oxidative stress. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.107G>T (p.G36V) alteration is located in exon 3 (coding exon 3) of the SCARA3 gene. This alteration results from a G to T substitution at nucleotide position 107, causing the glycine (G) at amino acid position 36 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
