Column Information
Name Type Discontinued?
1 VARIANT_ID NUMERIC No
The unique identifier (.1 item) for the variant record.
2 LINE INTEGER No
The line number for the information associated with this record. Multiple pieces of information can be associated with this record.
3 REPEAT_NUCLEOTIDES VARCHAR No
The sequence of the nucleotides in a single unit of the repeat expansion variant.
4 REPEAT_NUMBER INTEGER No
The number of times a sequence of nucleotides (in REPEAT_NUCLEOTIDES) is repeated.
5 REPEAT_NUMBER_LEADING INTEGER No
Repeat number is to record the repeated number in repeat expansion variant. For structured numeric values, this is the number used with the operator (or leading number if there is a range).
6 REPEAT_NUMBER_TRAILING INTEGER No
Repeat number is to record the repeated number in repeat expansion variant. For structured numeric values, this is the upper bound value if there is a range. Otherwise, this item is not populated.
7 RPT_NUM_COMPARE_OPERATO_C_NAME VARCHAR No
