Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_020439.3(CAMK1G):c.143T>A(p.Leu48His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000805 in 1,613,916 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. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L48F) has been classified as Uncertain significance.

Ambry Genetics

Nov 21, 2024

The c.143T>A (p.L48H) alteration is located in exon 3 (coding exon 2) of the CAMK1G gene. This alteration results from a T to A substitution at nucleotide position 143, causing the leucine (L) at amino acid position 48 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
