Genetic Variant DISP2:p.Pro38Ala (chr15-40358433-C-G) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

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

The NM_033510.3(DISP2):c.112C>G(p.Pro38Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000455 in 1,318,672 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 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. P38R) has been classified as Uncertain significance.

Genes affected

DISP2 (HGNC:19712): (dispatched RND transporter family member 2) This gene is one of two human homologs of a segment-polarity gene known as dispatched identified in Drosophila. The product of this gene may be required for normal Hedgehog (Hh) signaling during embryonic pattern formation. [provided by RefSeq, Jan 2017]

Collection Method: clinical testing

The c.112C>G (p.P38A) alteration is located in exon 1 (coding exon 1) of the DISP2 gene. This alteration results from a C to G substitution at nucleotide position 112, causing the proline (P) at amino acid position 38 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
