Genes affected

FGF10 (HGNC:3666): (fibroblast growth factor 10) The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein exhibits mitogenic activity for keratinizing epidermal cells, but essentially no activity for fibroblasts, which is similar to the biological activity of FGF7. Studies of the mouse homolog of suggested that this gene is required for embryonic epidermal morphogenesis including brain development, lung morphogenesis, and initiation of lim bud formation. This gene is also implicated to be a primary factor in the process of wound healing. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Pathogenic. The variant received 10 ACMG points.

• PM1: In a chain Fibroblast growth factor 10 (size 170) in uniprot entity FGF10_HUMAN there are 8 pathogenic changes around while only 2 benign (80%) in NM_004465.2
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 8 curated pathogenic missense variants (we use a threshold of 10). The gene has 2 curated benign missense variants. Gene score misZ: 0.85048 (below the threshold of 3.09). Trascript score misZ: 1.4672 (below the threshold of 3.09). GenCC associations: The gene is linked to lacrimoauriculodentodigital syndrome 3, LADD syndrome, aplasia of lacrimal and salivary glands, congenital heart defects, multiple types, craniosynostosis.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.941
• PP5: Variant 5-44388366-C-A is Pathogenic according to our data. Variant chr5-44388366-C-A is described in ClinVar as Pathogenic. ClinVar VariationId is 7531.Status of the report is no_assertion_criteria_provided, 0 stars.
