Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 2P and 7B. PM2BP4_ModerateBP7BS1

The NM_020708.5(SLC12A5):c.2376T>A(p.Ile792Ile) variant causes a splice region, synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000248 in 1,208,086 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. I792I) has been classified as Likely benign.

Genes affected

SLC12A5 (HGNC:13818): (solute carrier family 12 member 5) K-Cl cotransporters are proteins that lower intracellular chloride concentrations below the electrochemical equilibrium potential. The protein encoded by this gene is an integral membrane K-Cl cotransporter that can function in either a net efflux or influx pathway, depending on the chemical concentration gradients of potassium and chloride. The encoded protein can act as a homomultimer, or as a heteromultimer with other K-Cl cotransporters, to maintain chloride homeostasis in neurons. Alternative splicing results in two transcript variants encoding different isoforms. [provided by RefSeq, Sep 2008]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.43).

BP7

Synonymous conserved (PhyloP=-3.12 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.00000183 (2/1092710) while in subpopulation AFR AF = 0.0000922 (2/21686). AF 95% confidence interval is 0.0000163. There are 0 homozygotes in GnomAdExome4. There are 2 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
