Variant summary
Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP4_StrongBP6
The NM_000051.4(ATM):c.3577-6G>A variant causes a splice region, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000236 in 1,611,712 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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 Conflicting classifications of pathogenicity (no stars).

Variant summary: The ATM c.3577-6G>A variant involves the alteration of a non-conserved intronic nucleotide. One in silico tool predicts a benign outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. 3/5 predicted change of cryptic splicing sites. However, these predictions have yet to be confirmed by functional studies. This variant was found in 3/120616 control chromosomes at a frequency of 0.0000249, which does not exceed the estimated maximal expected allele frequency of a pathogenic ATM variant (0.0010005). In addition, one clinical diagnostic laboratory classified this variant as likely benign. The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or reputable databases/clinical diagnostic laboratories; nor evaluated for functional impact by in vivo/vitro studies. One internal sample also carried a disease variant in BRCA1 c.3869_3870delAA. Because of the absence of clinical information and the lack of functional studies, the variant is classified as a variant of uncertain significance (VUS)-possible benign until additional information becomes available. -
