DDG2P
Gene: LMNA
The DDG2P confidence category for the disease FAMILIAL PARTIAL LIPODYSTROPHY TYPE 2, OMIM:151660 is definitive. The allelic requirement, mutation consequence and cross cutting modifier are monoallelic_autosomal, altered gene product structure and potential IF respectively (PMIDs: 10587585;10655060).
The DDG2P confidence category for the disease EMERY-DREIFUSS MUSCULAR DYSTROPHY TYPE 2, OMIM:181350 is definitive. The allelic requirement, mutation consequence and cross cutting modifier are monoallelic_autosomal, absent gene product and potential IF respectively.
The DDG2P confidence category for the disease HUTCHINSON-GILFORD PROGERIA SYNDROME, OMIM:176670 is definitive. The allelic requirement, mutation consequence and cross cutting modifier are monoallelic_autosomal, altered gene product structure and potential IF respectively.
The DDG2P confidence category for the disease CHARCOT-MARIE-TOOTH DISEASE TYPE 2B1, OMIM:605588 is limited. The allelic requirement, mutation consequence and cross cutting modifier are biallelic_autosomal, uncertain and potential IF respectively.Created: 4 Oct 2023, 5:08 p.m. | Last Modified: 6 Oct 2023, 9:10 a.m.
