Genes affected

RETSAT (HGNC:25991): (retinol saturase) Predicted to enable all-trans-retinol 13,14-reductase activity. Predicted to be involved in retinol metabolic process. Located in membrane. [provided by Alliance of Genome Resources, Apr 2022]

RETSAT links:

ELMOD3 (HGNC:26158): (ELMO domain containing 3) This gene encodes a member of the engulfment and cell motility family of GTPase-activating proteins that regulate Arf GTPase proteins. Members of this family are defined by a conserved engulfment and cell motility domain. In rat cochlea, the encoded protein is found in stereocilia, kinocilia and cuticular plate of developing hair cells suggesting a function for this protein in cochlear sensory cells. An allelic variant of this family has been associated with autosomal recessive nonsyndromic deafness-88 in humans. Alternative splicing results in multiple transcript variants.

The c.82A>G (p.S28G) alteration is located in exon 1 (coding exon 1) of the RETSAT gene. This alteration results from a A to G substitution at nucleotide position 82, causing the serine (S) at amino acid position 28 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
