Genes affected
HPCAL4 (HGNC:18212): (hippocalcin like 4) The protein encoded by this gene is highly similar to human hippocalcin protein and hippocalcin like-1 protein. It also has similarity to rat neural visinin-like Ca2+-binding protein-type 1 and 2 proteins. This encoded protein may be involved in the calcium-dependent regulation of rhodopsin phosphorylation. The transcript of this gene has multiple polyadenylation sites. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2023The c.567G>A (p.M189I) alteration is located in exon 4 (coding exon 3) of the HPCAL4 gene. This alteration results from a G to A substitution at nucleotide position 567, causing the methionine (M) at amino acid position 189 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
