Genes affected

BCL2L14 (HGNC:16657): (BCL2 like 14) The protein encoded by this gene belongs to the BCL2 protein family. BCL2 family members form hetero- or homodimers and act as anti- or pro-apoptotic regulators that are involved in a wide variety of cellular activities. Overexpression of this gene has been shown to induce apoptosis in cells. Three alternatively spliced transcript variants encoding two distinct isoforms have been reported for this gene.

The c.131C>T (p.S44L) alteration is located in exon 2 (coding exon 1) of the BCL2L14 gene. This alteration results from a C to T substitution at nucleotide position 131, causing the serine (S) at amino acid position 44 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
