Vascular skin disorders
Gene: FLT4Comment on list classification: Inclusion of FLT4 should be reviewed by the GMS specialist team due to conflicting reviews.
Primary lymphoedema caused by heterozygous variants in this gene does not fit the panel scope and is more appropriate for R136 Primary lymphoedema. Since 2002, there has only been one report of a somatic variant causing skin capillary haemangiomas (PMID:11807987). There has been no evidence of germline variants causing a similar phenotype.Created: 25 Mar 2024, 2:25 p.m. | Last Modified: 25 Mar 2024, 2:25 p.m.
