Variant summary

Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM2PM5PP2PP3_ModeratePP5

The NM_000141.5(FGFR2):​c.758C>T​(p.Pro253Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P253R) has been classified as Pathogenic.

Genes affected
FGFR2 (HGNC:3689): (fibroblast growth factor receptor 2) The protein encoded by this gene is a member of the fibroblast growth factor receptor family, where amino acid sequence is highly conserved between members and throughout evolution. FGFR family members differ from one another in their ligand affinities and tissue distribution. A full-length representative protein consists of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of the protein interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. This particular family member is a high-affinity receptor for acidic, basic and/or keratinocyte growth factor, depending on the isoform. Mutations in this gene are associated with Crouzon syndrome, Pfeiffer syndrome, Craniosynostosis, Apert syndrome, Jackson-Weiss syndrome, Beare-Stevenson cutis gyrata syndrome, Saethre-Chotzen syndrome, and syndromic craniosynostosis. Multiple alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Jan 2009]

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr10-121520160-G-C is described in Lovd as [Pathogenic].
PP2
Missense variant in the FGFR2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 114 curated pathogenic missense variants (we use a threshold of 10). The gene has 24 curated benign missense variants. Gene score misZ: 2.402 (below the threshold of 3.09). Trascript score misZ: 4.4365 (above the threshold of 3.09). GenCC associations: The gene is linked to Pfeiffer syndrome type 3, Antley-Bixler syndrome, Pfeiffer syndrome type 2, Saethre-Chotzen syndrome, Beare-Stevenson cutis gyrata syndrome, Crouzon syndrome, Jackson-Weiss syndrome, Pfeiffer syndrome type 1, LADD syndrome 1, Pfeiffer syndrome, bent bone dysplasia syndrome 1, Antley-Bixler syndrome without genital anomalies or disordered steroidogenesis, familial scaphocephaly syndrome, McGillivray type, Apert syndrome, LADD syndrome.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.888
PP5
Variant 10-121520160-G-A is Pathogenic according to our data. Variant chr10-121520160-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 829801.We mark this variant Likely_pathogenic, oryginal submissions are: {Likely_pathogenic=2, Uncertain_significance=1}.
