a novel TIMP3 point mutation
Case: Jacobson_1995_Family_1_Patient_III-5, male, country of origin United States (PMID:8981947), onset in 4th or early 5th decade of life
DiseaseAssertion: Sorsby's fundus dystrophy
FamilyInfo: The variant was inherited by the proband rather than acquired de novo.
CasePresentingHPOs: HP:0011510 (Drusen), HP:0200056 (Macular scar), HP:0000608 (Macular degeneration), HP:0000603 (Central scotoma), HP:0025243 (Subretinal hemorrhage), HP:0000662 (Nyctalopia)
CaseHPOFreeText: Onset in the 4th or early 5th decade of life with drusen appearing first and progression to macular scarring (secondary to subretinal hemorrhage) and degeneration.
CaseNOTHPOs: N/A
CaseNOTHPOFreeText: N/A
CasePreviousTesting: SSCP using PCR-amplified exon 5 from TIMP3, followed by Sanger sequencing of the exon 5 PCR product.
GenotypingMethod: PCR amplification of exon 5, followed by enzyme digestion with the Bbv1 restriction endonuclease.
PreviouslyPublished: N/A
SupplementalData: N/A
Variant: Patients harbor the NM_000362.5(TIMP3):c.568G>T (p.Gly190Cys) missense variant.
CAID: CA411540415
gnomAD: Variant is absent from gnomAD.
VariantEvidence: This missense variant within exon 5 of TIMP3 results in an unpaired Cys residue.
