Here is my attempt, I've only replace fields that start with two or more ., characters as you seem to have fields ending with these characters in your desired output:

Code:
awk '
FNR==1 {
   if (NR>1) print
   next
}
{ key = $1 FS $2 }
FNR==NR{
    hgvs_c[key]=$6
    hgvs_p[key]=$7
    next
}
key in hgvs_c {
   $7 = hgvs_c[key]
   $8 = hgvs_p[key]
}
{ gsub(/\t[\.,]{2,}[^\t]*/, "\t-") }
1' FS='\t' OFS='\t' file2 file1

NAME
pr - print file SYNOPSIS
pr [ option ... ] [ file ... ] DESCRIPTION
Pr produces a printed listing of one or more files on its standard output. The output is separated into pages headed by a date, the name of the file or a specified header, and the page number. With no file arguments, pr prints its standard input. Options apply to all following files but may be reset between files: -n Produce n-column output. +n Begin printing with page n. -b Balance columns on last page, in case of multi-column output. -d Double space. -en Set the tab stops for input text every n spaces. -h Take the next argument as a page header (file by default). -in Replace sequences of blanks in the output by tabs, using tab stops set every n spaces. -f Use formfeeds to separate pages. -ln Take the length of the page to be n lines instead of the default 66. -m Print all files simultaneously, each in one column. -n Number the lines of each file. -on Offset the left margin n character positions. -sc Separate columns by the single character c instead of aligning them with white space. A missing c is taken to be a tab. -t Do not print the 5-line header or the 5-line trailer normally supplied for each page. -wn For multi-column output, take the width of the page to be n characters instead of the default 72.
