Variant summary

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

The NM_153229.3(TMEM92):c.431C>T(p.Pro144Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000558 in 1,613,736 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. P144S) has been classified as Uncertain significance.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.431C>T (p.P144L) alteration is located in exon 6 (coding exon 5) of the TMEM92 gene. This alteration results from a C to T substitution at nucleotide position 431, causing the proline (P) at amino acid position 144 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
