Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_173650.3(DNAJC5G):​c.377C>A​(p.Thr126Lys) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 12/19 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★).

The c.377C>A (p.T126K) alteration is located in exon 5 (coding exon 3) of the DNAJC5G gene. This alteration results from a C to A substitution at nucleotide position 377, causing the threonine (T) at amino acid position 126 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
