Genes affected

SEPTIN2 (HGNC:7729): (septin 2) Enables identical protein binding activity. Predicted to be involved in several processes, including cilium assembly; regulation of exocytosis; and smoothened signaling pathway. Predicted to act upstream of or within regulation of L-glutamate import across plasma membrane and regulation of protein localization. Located in several cellular components, including cytoskeleton; photoreceptor connecting cilium; and sperm annulus. Part of septin complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.152C>T (p.S51L) alteration is located in exon 5 (coding exon 3) of the SEPT2 gene. This alteration results from a C to T substitution at nucleotide position 152, causing the serine (S) at amino acid position 51 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
