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]
LINC02245 (HGNC:53134): (long intergenic non-protein coding RNA 2245)
