Genetic Variant IGSF23:p.Pro141Ser (chr19-44627449-C-T) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate

The NM_001205280.2(IGSF23):c.421C>T(p.Pro141Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000011 in 1,548,354 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 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. P141H) has been classified as Uncertain significance.

Genes affected

IGSF23 (HGNC:40040): (immunoglobulin superfamily member 23) This gene encodes a protein that has one immunoglobulin (Ig) domain and is a member of the immunoglobulin superfamily. Proteins in this superfamily are usually found on or in cell membranes and act as receptors in immune response pathways. [provided by RefSeq, Nov 2011]
