Genes affected

SLC1A4 (HGNC:10942): (solute carrier family 1 member 4) The protein encoded by this gene is a sodium-dependent neutral amino acid transporter for alanine, serine, cysteine, and threonine. Defects in this gene have been associated with developmental delay, microcephaly, and intellectual disability. [provided by RefSeq, Jan 2017]

This sequence change creates a premature translational stop signal (p.Ser507*) in the SLC1A4 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 26 amino acid(s) of the SLC1A4 protein. This variant is present in population databases (rs200617042, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with SLC1A4-related conditions. ClinVar contains an entry for this variant (Variation ID: 436740). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
