Variant summary
Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP6BS1
The NM_001161352.2(KCNMA1):c.15_16insAGC(p.Gly5_Gly6insSer) variant causes a inframe insertion change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000716 in 1,523,288 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. G5G) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 21, 2023 | This variant, c.15_16insAGC, results in the insertion of 1 amino acid(s) of the KCNMA1 protein (p.Gly5_Gly6insSer), but otherwise preserves the integrity of the reading frame. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has been observed in individual(s) with drug resistant focal seizures (PMID: 29933521). ClinVar contains an entry for this variant (Variation ID: 300975). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
