Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_006161.3(NEUROG1):c.548C>T(p.Ala183Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000162 in 1,608,946 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 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. A183E) has been classified as Benign.

The c.548C>T (p.A183V) alteration is located in exon 1 (coding exon 1) of the NEUROG1 gene. This alteration results from a C to T substitution at nucleotide position 548, causing the alanine (A) at amino acid position 183 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
