Genetic Variant DAP:p.Arg65Trp (chr5-10683531-G-A) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_004394.3(DAP):c.193C>T(p.Arg65Trp) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000558 in 1,613,898 control chromosomes in the GnomAD database, with no homozygous occurrence. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R65L) has been classified as Uncertain significance.

Genes affected

DAP (HGNC:2672): (death associated protein) This gene encodes a basic, proline-rich, 15-kD protein. The protein acts as a positive mediator of programmed cell death that is induced by interferon-gamma. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, May 2014]

Collection Method: clinical testing

The c.193C>T (p.R65W) alteration is located in exon 3 (coding exon 3) of the DAP gene. This alteration results from a C to T substitution at nucleotide position 193, causing the arginine (R) at amino acid position 65 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
