Invitae RCV000204217 SCV000259812 uncertain significance Li-Fraumeni syndrome 2015-08-07 criteria provided, single submitter clinical testing This sequence change replaces tyrosine with aspartic acid at codon 234 of the TP53 protein (p.Tyr234Asp). The tyrosine residue is highly conserved and there is a large physicochemical difference between tyrosine and aspartic acid. This variant is not present in population databases and has been reported in the literature. This variant was reported in an individual affected with chronic lymphocytic leukemia (PMID: 21232794). It has also been reported in the tumor of a patient with colorectal cancer (PMID: 22982087). Experimental studies in vitro have shown that this missense change may lead to defective transactivation (PMID: 21232794). Other missense mutations, p.Tyr234Cys and p.Tyr234His, have been reported at the same codon in individuals affected with Li-Fraumeni syndrome as well as other isolated cancers (PMID: 12695689, 17606709, 23894400). Experimental studies of these missense mutations suggest that this amino acid may be essential for protein function (PMID: 9290701, 21232794, 21343334). In summary, clinical and experimental evidence suggests that other missense mutations at this position may lead to disrupted protein function. However, evidence directly related this p.Tyr234Asp variant is limited. For these reasons, this change has been classified as a Variant of Uncertain Significance.
