Variant chr15-65384991-G-A details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_020962.3(IGDCC4):c.3305C>T(p.Thr1102Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000745 in 1,610,780 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T1102A) has been classified as Likely benign.

Ambry Genetics

Feb 12, 2024

The c.3305C>T (p.T1102M) alteration is located in exon 19 (coding exon 19) of the IGDCC4 gene. This alteration results from a C to T substitution at nucleotide position 3305, causing the threonine (T) at amino acid position 1102 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
