Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_032843.5(FIBCD1):c.1129G>C(p.Asp377His) variant causes a missense, splice region change. The variant allele was found at a frequency of 0.00000344 in 1,453,124 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D377N) has been classified as Uncertain significance.

The c.1129G>C (p.D377H) alteration is located in exon 7 (coding exon 7) of the FIBCD1 gene. This alteration results from a G to C substitution at nucleotide position 1129, causing the aspartic acid (D) at amino acid position 377 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
