Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PM5PP2PP3_Strong

The NM_023110.3(FGFR1):​c.1968G>C​(p.Lys656Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K656E) has been classified as Likely pathogenic.

Genes affected
FGFR1 (HGNC:3688): (fibroblast growth factor receptor 1) The protein encoded by this gene is a member of the fibroblast growth factor receptor (FGFR) 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 binds both acidic and basic fibroblast growth factors and is involved in limb induction. Mutations in this gene have been associated with Pfeiffer syndrome, Jackson-Weiss syndrome, Antley-Bixler syndrome, osteoglophonic dysplasia, and autosomal dominant Kallmann syndrome 2. Chromosomal aberrations involving this gene are associated with stem cell myeloproliferative disorder and stem cell leukemia lymphoma syndrome. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 11 ACMG points.

PM1
In a domain Protein kinase (size 289) in uniprot entity FGFR1_HUMAN there are 78 pathogenic changes around while only 2 benign (98%) in NM_023110.3
PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr8-38414790-T-C is described in Lovd as [Likely_pathogenic].
PP2
Missense variant in the FGFR1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 93 curated pathogenic missense variants (we use a threshold of 10). The gene has 28 curated benign missense variants. Gene score misZ: 2.4852 (below the threshold of 3.09). Trascript score misZ: 4.2642 (above the threshold of 3.09). GenCC associations: The gene is linked to hypogonadotropic hypogonadism 2 with or without anosmia, encephalocraniocutaneous lipomatosis, hypogonadotropic hypogonadism, tooth agenesis, isolated trigonocephaly, Pfeiffer syndrome type 1, Jackson-Weiss syndrome, Pfeiffer syndrome, Kallmann syndrome, septooptic dysplasia, hypogonadotropic hypogonadism 7 with or without anosmia, holoprosencephaly, osteoglophonic dwarfism, Hartsfield-Bixler-Demyer syndrome.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.975
