Genes affected

HPCAL1 (HGNC:5145): (hippocalcin like 1) The protein encoded by this gene is a member of neuron-specific calcium-binding proteins family found in the retina and brain. It is highly similar to human hippocalcin protein and nearly identical to the rat and mouse hippocalcin like-1 proteins. It may be involved in the calcium-dependent regulation of rhodopsin phosphorylation and may be of relevance for neuronal signalling in the central nervous system. Several alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Apr 2012]

Feb 23, 2023

The c.236C>G (p.T79S) alteration is located in exon 4 (coding exon 1) of the HPCAL1 gene. This alteration results from a C to G substitution at nucleotide position 236, causing the threonine (T) at amino acid position 79 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
