Primary Lymphoedema & Lymphatic Malformations
- Hennekam Syndrome Type 2Autosomal recessive
A condition caused by changes in FAT4 that combines lymphoedema, swollen lymph vessels in the gut and variable learning difficulties.
- 2 GenCC submitters rate it definitive or strong
Inheritance
- Autosomal recessive
- It takes a changed copy from each parent. With one, you are a carrier and usually unaffected; when both parents are carriers, each child has a one-in-four chance of inheriting two.
How FAT4 is laid out
- Coding sequence
- Untranslated region
- Intron
- Direction of transcription
- Known disease-causing sites
- Stretches short reads find hard
Exons of the gene's MANE Select transcript (release v1.5), from NCBI and EMBL-EBI, on the GRCh38 reference genome.
Chromosome bands from UCSC's GRCh38 ideogram (2022-10-29).
Nearby genes from Ensembl release 116, on GRCh38.
Exons make up 17.2 kb of the gene's 178 kb; 14,952 of those bases code for the protein.
How a genome test reads FAT4
14
positions in FAT4 where ClinVar classes a change as pathogenic or likely pathogenic
None of them falls in a region short reads find hard.
A whole genome covers all 178 kb of FAT4, introns included, not only the 17.2 kb of exons.
