The c.4347G>T (p.L1449F) alteration is located in exon 24 (coding exon 24) of the CCDC141 gene. This alteration results from a G to T substitution at nucleotide position 4347, causing the leucine (L) at amino acid position 1449 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

ClinVar contains an entry for this variant (Variation ID: 1500313). 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with CCDC141-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 1449 of the CCDC141 protein (p.Leu1449Phe). -

The CCDC141 c.4347G>T variant is predicted to result in the amino acid substitution p.Leu1449Phe. To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
