346-565 |
Sentence |
denotes |
We analyzed the HEXA gene of one pseudodeficient subject and identified both a C739-to-T substitution that changes Arg247----Trp on one allele and a previously identified Tay-Sachs disease mutation on the second allele. |

| TextSentencer_T6 |
649-860 |
Sentence |
denotes |
This allele accounted for 32% (20/62) of non-Jewish enzyme-defined Tay-Sachs disease carriers but for none of 36 Jewish enzyme-defined carriers who did not have one of three known mutations common to this group. |
| T6 |
649-860 |
Sentence |
denotes |
This allele accounted for 32% (20/62) of non-Jewish enzyme-defined Tay-Sachs disease carriers but for none of 36 Jewish enzyme-defined carriers who did not have one of three known mutations common to this group. |
| TextSentencer_T7 |
861-962 |
Sentence |
denotes |
The C739-to-T allele, together with a "true" Tay-Sachs disease allele, causes Hex A pseudodeficiency. |
| T7 |
861-962 |
Sentence |
denotes |
The C739-to-T allele, together with a "true" Tay-Sachs disease allele, causes Hex A pseudodeficiency. |
| TextSentencer_T8 |
963-1240 |
Sentence |
denotes |
Given both the large proportion of non-Jewish carriers with this allele and that standard biochemical screening cannot differentiate between heterozygotes for the C739-to-T mutations and Tay-Sachs disease carriers, DNA testing for this mutation in at-risk couples is essential. |
