Summaries for Hypomagnesemia 5, Renal, with or Without Ocular Involvement

UniProtKB/Swiss-Prot : 74 Hypomagnesemia 5, renal, with or without ocular involvement: A progressive renal disease characterized by primary renal magnesium wasting with hypomagnesemia, hypercalciuria and nephrocalcinosis associated with severe ocular abnormalities such as bilateral chorioretinal scars, macular colobomata, significant myopia and nystagmus. The renal phenotype is virtually undistinguishable from that of patients with HOMG3.

MalaCards based summary : Hypomagnesemia 5, Renal, with or Without Ocular Involvement, also known as hypomagnesemia 5, renal, with ocular involvement, is related to familial primary hypomagnesemia with hypercalciuria and nephrocalcinosis and hypomagnesemia 3, renal. An important gene associated with Hypomagnesemia 5, Renal, with or Without Ocular Involvement is CLDN19 (Claudin 19). Affiliated tissues include kidney and eye, and related phenotypes are nystagmus and abnormality of retinal pigmentation

Disease Ontology : 12 A hypomagnesemia characterized by autosomal recessive inheritance of renal magnesium wasting with hypercalcinosis, progressive renal failure and severe ocular involvement that has material basis in homozygous mutation in the CLDN19 gene on chromosome 1p34.2.

OMIM : 57 HOMG5 is an autosomal recessive disorder characterized by severe renal magnesium wasting, progressive renal failure, nephrocalcinosis, and severe visual impairment (Konrad et al., 2006). Amelogenesis imperfecta may also be present in some patients (Yamaguti et al., 2017). For a discussion of genetic heterogeneity of renal hypomagnesemia, see 602014. (248190)
