Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3
The NM_024692.6(CLIP4):c.263T>C(p.Ile88Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000138 in 1,597,746 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).
CLIP4 (HGNC:26108): (CAP-Gly domain containing linker protein family member 4) Predicted to enable microtubule plus-end binding activity. Predicted to be involved in cytoplasmic microtubule organization. Located in intracellular membrane-bounded organelle. [provided by Alliance of Genome Resources, Apr 2022]
Review Status: criteria provided, single submitter
Collection Method: clinical testing
The c.263T>C (p.I88T) alteration is located in exon 3 (coding exon 2) of the CLIP4 gene. This alteration results from a T to C substitution at nucleotide position 263, causing the isoleucine (I) at amino acid position 88 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
