Description

The Pro77Leu variant in TNNT2 has been identified in 1 individual with HCM/SCD ( Varnava 2001) as well as in 1/8600 European American chromosomes from a broad po pulation by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS /; dbSNP rs144900708). Proline (Pro) at position 77 is conserved in mammals and some evolutionarily distant species, but frog and stickleback carry a leucine (L eu; this variant) at this position suggesting that this change may be tolerated. Other computational analyses (biochemical amino acid properties, AlignGVGD, Pol yPhen2, and SIFT) suggest that this variant may not impact the protein, though t his information is not predictive enough to rule out pathogenicity. Additional s tudies are needed to fully assess the clinical significance of this variant.
