Genotyping of the likely causal 16-bp SPTBN4 frameshift deletion in five carrier-by-carrier litters. The sum per genotype class is indicated in bold.
| Litter ID | # Genotyped progeny | # Wild type | # Deletion carrier | # Homozygotes |
|---|---|---|---|---|
| 1 | 12 | 3 | 5 | 4 |
| 2 | 12 | 0 | 8 | 4 |
| 3 | 11 | 0 | 5 | 6 |
| 4 | 8 | 1 | 5 | 2 |
| 5 | 10 | 4 | 3* | 3 |
| SUM | 53 | 8 (15.1%) | 26 (49.1%) | 19 (35.8%) |
All animals homozygous for the deletion died within 48 h after birth.
*One piglet died within 24 h after birth.
