Genes affected

CREB3L1 (HGNC:18856): (cAMP responsive element binding protein 3 like 1) The protein encoded by this gene is normally found in the membrane of the endoplasmic reticulum (ER). However, upon stress to the ER, the encoded protein is cleaved and the released cytoplasmic transcription factor domain translocates to the nucleus. There it activates the transcription of target genes by binding to box-B elements. [provided by RefSeq, Jun 2013]

The c.236C>T (p.T79M) alteration is located in exon 2 (coding exon 2) of the CREB3L1 gene. This alteration results from a C to T substitution at nucleotide position 236, causing the threonine (T) at amino acid position 79 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 79 of the CREB3L1 protein (p.Thr79Met). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with CREB3L1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1417122). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
