Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_018169.4(RESF1):ā€‹c.318C>Gā€‹(p.His106Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,800 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely benign in UniProt.

Collection Method: clinical testing

The c.318C>G (p.H106Q) alteration is located in exon 4 (coding exon 1) of the KIAA1551 gene. This alteration results from a C to G substitution at nucleotide position 318, causing the histidine (H) at amino acid position 106 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
