This seems to come close to what you said you wanted to do:
Code:
awk '
/^[[:alnum:]]/ {
	h = $0
	np = 0
}
$3 == "TSC1" {
	if(np++ == 0)
		print h
	print
}' file

but with the sample input you provided, it only prints:
Code:
name      31    Index   Chromosomal Position    Gene    Inheritance
                  82    135782221       TSC1    AD
                  81    135782026       TSC1    AD

Since TSC1 does not appear anywhere in your input file after names3, I have no idea how you got the rest of the output you said you desired.

As always, if anyone wants to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk (not nawk for this script).

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF
