Genes affected

OLFM1 (HGNC:17187): (olfactomedin 1) This gene product shares extensive sequence similarity with the rat neuronal olfactomedin-related ER localized protein. While the exact function of the encoded protein is not known, its abundant expression in brain suggests that it may have an essential role in nerve tissue. Several alternatively spliced transcripts encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.1150G>A (p.A384T) alteration is located in exon 6 (coding exon 6) of the OLFM1 gene. This alteration results from a G to A substitution at nucleotide position 1150, causing the alanine (A) at amino acid position 384 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
