Clefting disorders v0.144 GDF11 Zornitza Stark Publications for gene: GDF11 were set to PubMed: 31215115
Clefting disorders v0.143 GDF11 Chirag Patel Classified gene: GDF11 as Green List (high evidence)
Clefting disorders v0.143 GDF11 Chirag Patel Gene: gdf11 has been classified as Green List (High Evidence).
Clefting disorders v0.142 GDF11 Chirag Patel edited their review of gene: GDF11: Added comment: Ravenscroft et al. (2021) report 6 probands who presented with craniofacial (5/6), vertebral (5/6), neurological (6/6), visual (4/6), cardiac (3/6), auditory (3/6), and connective tissue abnormalities (3/6). They found de novo and inherited variants in GDF11. gdf11 mutant zebrafish showed craniofacial abnormalities and body segmentation defects that matched some patient phenotypes. Expression of the patients’ variants in the fly showed that one nonsense variant in GDF11 is a severe loss-of-function (LOF) allele whereas the missense variants are partial LOF variants.; Changed rating: GREEN; Changed publications: PubMed: 31215115, 34113007; Changed phenotypes: Vertebral hypersegmentation and orofacial anomalies (VHO), OMIM #619122

Clefting disorders v0.48 GDF11 Zornitza Stark Marked gene: GDF11 as ready
Clefting disorders v0.48 GDF11 Zornitza Stark Gene: gdf11 has been classified as Red List (Low Evidence).
Clefting disorders v0.44 FST Chirag Patel gene: FST was added
gene: FST was added to Clefting_GEL. Sources: Expert list
Mode of inheritance for gene: FST was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: FST were set to PubMed: 31215115
Phenotypes for gene: FST were set to orofacial clefting
Review for gene: FST was set to RED
Added comment: In a cohort of 72 families with orofacial clefting, Cox et al. (2019) performed exome sequencing and identified a father and 2 daughters (family 22) with cleft lip and palate who were heterozygous for missense variant (C56Y) in FST. A highly conserved residue within the 63-residue N-terminal domain. The variant was not found in the unaffected paternal grandmother or in the gnomAD database. Classed as a VUS. Functional analysis in transfected HEK293T cells, using a stable cell line sensitive to stimulation by the FST downstream target GDF11, demonstrated that wildtype FST efficiently and completely antagonized GDF11-stimulated reporter activity. In contrast, the C56Y mutant did not significantly inhibit the stimulation of reporter activity, regardless of the amount of mutant vector transfected.

Clefting disorders v0.42 GDF11 Chirag Patel gene: GDF11 was added
gene: GDF11 was added to Clefting_GEL. Sources: Expert list
Mode of inheritance for gene: GDF11 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: GDF11 were set to PubMed: 31215115
Phenotypes for gene: GDF11 were set to Vertebral hypersegmentation and orofacial anomalies (VHO), MIM#619122
Review for gene: GDF11 was set to RED
Added comment: In 5 affected members over 3 generations of a family segregating vertebral hypersegmentation and orofacial anomalies, Cox et al. (2019) identified heterozygosity for a missense mutation in the GDF11 gene (R298Q) that was not found in unaffected family members or in public variant databases. Functional analysis demonstrated that the R298Q substitution prevents cleavage to the active form of the protein, resulting in loss of function.
