Variant summary

Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM2PM5PP2PP3_Strong

The NM_001010898.4(SLC6A17):​c.1898C>T​(p.Pro633Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,724 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P633R) has been classified as Likely pathogenic.

Genes affected
SLC6A17 (HGNC:31399): (solute carrier family 6 member 17) The protein encoded by this gene is a member of the SLC6 family of transporters, which are responsible for the presynaptic uptake of most neurotransmitters. The encoded vesicular transporter is selective for proline, glycine, leucine and alanine. In mouse, the strongest expression of this gene was in cortical and hippocampal tissues where expression increased during embryonic brain development and peaked postnatally. Defects in this gene cause a form of autosomal recessive intellectual disability. [provided by RefSeq, Jul 2017]

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr1-110198158-C-G is described in Lovd as [Likely_pathogenic].
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SLC6A17. . Gene score misZ 2.3852 (greater than the threshold 3.09). Trascript score misZ 3.6036 (greater than threshold 3.09). GenCC has associacion of gene with progressive essential tremor-speech impairment-facial dysmorphism-intellectual disability-abnormal behavior syndrome, schizophrenia.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.976
