<p>The Finnish type of systemic amyloidosis is characterized clinically by a unique constellation of features including lattice corneal dystrophy, and cranial neuropathy, bulbar signs, and skin changes. Some patients may develop peripheral neuropathy and renal failure.

<strong>Description</strong>

</h4>
</div>
<span class="mim-text-font">
<p>The Finnish type of systemic amyloidosis is characterized clinically by a unique constellation of features including lattice corneal dystrophy, and cranial neuropathy, bulbar signs, and skin changes. Some patients may develop peripheral neuropathy and renal failure. The disorder is usually inherited in an autosomal dominant pattern; however, homozygotes with a more severe phenotype have also been reported (Meretoja, 1973). </p><p>Finnish hereditary amyloidosis, also known as Meretoja syndrome or AGel amyloidosis, is one of the most common diseases in the Finnish disease heritage. Symptoms commonly appear by age 40, with the first finding usually corneal lattice dystrophy (CLD), diagnosed by an ophthalmologist. Impaired vision, polyneuropathy, facial nerve paresis, and cutis laxa follow. These symptoms may develop slowly and simultaneously, since amyloid accumulates systemically at a constant rate (summary by Nikoskinen et al., 2015). </p><p>For a discussion of genetic heterogeneity of hereditary systemic amyloidosis, see AMYLD1 (105210).</p>

<strong>Clinical Features</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>In a massive investigation in Finland, Meretoja (1973) identified 207 affected persons. Two patients, whose parents were affected and who were more severely affected than the others, were thought to represent homozygosity. A few of the patients developed nephrotic syndrome and renal failure and some had cardiac involvement. Amyloid involvement was rather widespread at autopsy. Meretoja et al. (1978) collected 307 patients in Finland. </p><p>Klintworth (1967) presented evidence that corneal dystrophy of the lattice type is a local variety of amyloidosis. Lattice corneal dystrophy accompanied systemic amyloidosis of the Finnish type. </p><p>Three Czechoslovakian sisters with bulbar palsy, 'cutis hyperelastica,' and lattice dystrophy of the cornea, reported by Klaus et al. (1959), may have had this disorder. Cases were reported from the United States by Sack et al. (1981), Purcell et al. (1983), Darras et al. (1986), and Starck et al. (1991); from Holland by Winkelman et al. (1971); and from Denmark by Boysen et al. (1979). </p><p>One of the patients reported by Sack et al. (1981) had onset of facial paralysis, which began as inability to control a drooping lower lip, at the age of about 56; the lip became strikingly protuberant and everted with exposure of the lower gingival mucosa. Five years after onset he could not wrinkle his forehead and there was an intermittent twitch of the right side of the lower lip. The extraocular muscles were affected only minimally and there was no ptosis. A striking feature was laxity of the skin, which raised the question of cutis laxa. Slit-lamp examination showed a lattice type of corneal opacity bilaterally. The mother had the identical disorder beginning at about the same stage of life. The proband had bulbar manifestations. </p><p>Kiuru (1992) reported the clinical findings of 30 patients. Signs of cranial neuropathy especially affecting the facial nerve were found in all, and peripheral polyneuropathy mainly affecting vibration and touch senses was demonstrated in 26 patients. Kiuru et al. (1994) studied the autonomic nervous system and heart in 30 patients. Minor autonomic nervous system dysfunction was found in most patients, but clinically significant autonomic dysfunction or cardiopathy was not characteristic. </p><p>Akiya et al. (1996) reported a Japanese brother and half sister with lattice corneal dystrophy as part of Finnish-type amyloidosis. The authors referred to the Finnish type as FAP type IV. The patients were 70 and 68 years old. </p><p>Potrc et al. (2021) reported 6 members of a family with Finnish-type amyloidosis. Family members had corneal dystrophy (5/6), loose skin (5/6), and cardiac arrhythmia requiring treatment with an implantable cardioverter defibrillator (3/6). One patient had bilateral optic neuropathy, which may be related to the disease and is critical to recognize before corneal transplantation. Histopathologic analysis of the eyelid skin showed atrophic epidermis and dermis and amyloid deposits around hair follicles. </p><p>Mullany et al. (2021) reported 2 unrelated families with Finnish-type amyloidosis, one with an affected female without a family history of the disease and the other with affected father, son, and daughter. All 4 patients had polymorphic corneal stromal opacities, dermatochalasis requiring upper eyelid blepharoplasty, and dry eyes. The father and son had open-angle glaucoma. Systemic features included cutis laxa in all 4 patients, proteinuria in the daughter, cardiac findings in the father (sinus bradycardia) and the daughter (supraventricular tachycardia and idiopathic cardiomyopathy), and hypothyroidism in the son and daughter. </p>

<p>Maury et al. (1990) studied amyloid fibrils isolated from the kidney of a patient with the Finnish form. The amino acid sequence determined for part of the protein was identical to that deduced for plasma gelsolin in the region of amino acids 235-269. Using PCR and allele-specific oligonucleotide hybridization analysis of genomic DNA in patients with this disorder, Maury et al. (1990) identified a 654G-A transition in the GSN gene, resulting in an asp187-to-asn substitution (D187N; 137350.0001), in all 5 unrelated patients studied, but not in 45 unrelated control subjects. In a family study, the mutant gene was demonstrated in all members with clinical symptoms of the disease, as well as in 1 asymptomatic family member who was thought to represent a presymptomatic gene carrier. </p><p>Haltia et al. (1990) likewise showed that the amyloid in this disorder is antigenically and structurally related to gelsolin. The same mutation in gelsolin (asp187-to-asn) has been found in all Finnish families studied to date (Maury et al., 1990; Paunio et al., 1992; de la Chapelle et al., 1992; Haltia et al., 1992; Sipila and Aula, 2002); furthermore, it was also found in the affected son of the proband of the Scottish-American family reported by Sack et al. (1981); see de la Chapelle et al. (1992). </p><p>Maury (1993) reported the findings in 2 sisters who were homozygous for the D187N mutation in gelsolin. In both, the disease was unusually severe, manifesting with nephrotic syndrome and end-stage renal failure. Immunohistochemical studies of the kidneys demonstrated heavy glomerular deposits of gelsolin-derived amyloid. Immunostaining also demonstrated gelsolin in the tubular epithelium, where it was Congo-red negative. </p><p>In 6 members of a family with Finnish-type amyloidosis, Potrc et al. (2021) identified a heterozygous missense mutation in the GSN gene (E580K; 137350.0003). The mutation, which was found by exome sequencing, segregated with disease in the family and was not present in the gnomAD database. The affected residue was located in the G5 domain, which is homologous to the second domain, which contains D187N (137350.0001), the most common pathogenic variant. </p><p>In 2 unrelated families segregating Finnish-type amyloidosis, one with a single affected person and the other with 3 first-degree relatives, Mullany et al. (2021) identified heterozygous mutations in the GSN gene. In the single affected person, the classic D187N mutation (also referred to as D214N) was identified. In the 3 affected family members (father, son, and daughter), a trp493-to-arg (W493R; 137350.0004) mutation was identified. The W493R variant was the first to be located in the G4 domain. Immunohistochemical studies on corneal tissue from the proband in the family with the W493R variant identified gelsolin protein within histologically defined corneal amyloid deposits. </p>
